Jonathan Ross, Abbey Clancey and Gok Wan are to appear in a celebrity version of 'The Great British Bake Off' for Comic Relief.
The trio of stars have been shooting the charity special at Valentines Mansion in Ilford, Essex, and chat show host Jonathan, 53, has reportedly been on top form, cracking out some euphemistic one-liners in the tent which are set to have audiences howling.
A show insider told the Daily Mirror newspaper: "The celebrity special is going to be absolutely hilarious. Jonathan was being a real joker on set. He came out with some tasty double entendres that would make even Mel and Sue blush.
"Unfortunately his baking didn't quite make the same impact."
But while Jonathan has been focusing his attention on his gags rather than his gateaux, model Abbey - the wife of soccer player Peter Crouch - has her eyes on the prize and is determined to claim the culinary crown.
She reportedly told the show's crew: "I'm here to win it with my dumplings and cheese straws."
And it seems her efforts haven't gone unnoticed, with the notoriously tough judges Paul Hollywood and Mary Berry being pleasantly surprised by the 28-year-old blonde beauty's talents in the kitchen.
The insider added: "Abbey was having a whale of a time. She impressed the judges with her cooking and had a real skill with the dough."
Sadly for 40-year-old Gok his dish fell flat, with judge Paul commenting that it had "more style than substance".
The one-off celebrity special of the hit BBC1 show is set to air in the New Year.

Caroline Flack is "really high on dance".
The former 'Xtra Factor' presenter has admitted all she ever thinks about nowadays is her routines since she signed up for 'Strictly Come Dancing', but admitted the intense training sessions have been a lot tougher than she thought they would be.
Speaking at the Hilton rooftop bar at London's Wembley to celebrate the transformation of the iconic arch at Wembley Stadium connected by EE, she exclusively told BANG Showbiz: "It's much harder than I thought.
"I'm really high on dance right now. That's all I've been thinking about and I love it."
The 34-year-old beauty insists people shouldn't bet on her to win the show just yet and has tipped Radio 1 DJ Scott Mills to do well in the competition.
She added: "I've only seen Scott dance and he was brilliant.
"I wouldn't put any money on me get though - no one has seen me dance!"
Scott returned the compliment, insisting Caroline is one to watch on the show, and insisted he isn't worried about getting any stick from tough judge Craig Revel Horwood.
He said: "The training has been really tough. I think Caroline could do really well, I watched her today and she was brilliant.
"I love the drama with Craig. He's different off screen, he's really nice and then I think actually I know what you are really like."
While Caroline doesn't think people should place a bet on her just yet, those keen for a bit of value might like to note she is 13/2 fifth favourite with William Hill, while Scott is a huge 66/1 outsider.
Pixie Lott is currently 7/2 favourite followed by former rugby player Thom Evans (4/1) and The Saturdays singer Frankie Sandford (5/1).
William Hill spokesman Rupert Adams said: "Finally we get a chance to see how good this year's contestants are - We will be particularly interested to seeing Pixie and Frankie who between them have attracted almost half the bets!"
Caroline and Scott attended a party at the Hilton rooftop bar to celebrate the transformation of the iconic arch at Wembley Stadium connected by EE. Multi-coloured LED floodlights have been installed as part EE's partnership with the stadium.

Mutya Buena has been declared bankrupt.
The MKS singer was given the order by a High Court Judge earlier this week due to a reported unpaid tax bill, but her representatives told The Sun newspaper she is blaming the bankruptcy on an "administrative error".
According to paperwork lodged with Companies House, the 29-year-old star owed her company God Made Me Funky around £22,500 and the organisation only managed to register a profit of £902 in March 2013.
What's more, her company Sacred Three Limited is reportedly £10,000 in debt.
MKS - who are completed by her fellow former Sugababes founding members Siobhan Donaghy and Keisha Buchanan - haven't released any material since September but Mutya's representatives insists she "continues to write and record with the band".
Following their comeback, the group - also known as Mutya, Keisha, Siobhan - released single 'Flatline' but it only made number 50 in the UK chart.
However, Mutya is not the only singer popular in the early 2000s who has recently been made bankrupt.
Just last month, Blue singer Antony Costa declared himself bankrupt, following in the footsteps of his fellow bandmates Duncan James and Simon Webbe who both declared themselves bankrupt last year after they were unable to pay their debts.
Atomic Kitten singer Kerry Katona - the previous face of payday loan company Cash Lady - has been declared bankrupt twice, in 2008 and last year, and as a result she asked for money from her wedding guests at her nuptials to George Kay earlier this month to help feed her children.
Kerry - who has kids Molly, 13, Lilly Sue, 11, Heidi, seven, and Max, six, from previous relationships and five-month-old Dylan-George with George - said: "I have asked for money. Just a fiver in a card will do. I'm bankrupt and I've got five kids to feed."
Several other stars including S Club 7 pair Jo O'Meara and Paul Cattermole, who are set to make a comeback with the band, have also both faced bankruptcy, as has Westlife's Shane Filan.

Kendra Wilkinson Baskett has flushed her wedding ring down the toilet.
The 'Kendra On Top' star sparked speculation her marriage to Hank Baskett was over amid claims he had cheated on her with a transsexual woman after she stepped out without the jewellery, but she has admitted that she got rid of the band because she was so furious about the allegations.
Discussing what happened in the aftermath of hearing the claims, Kendra said: "I take my wedding rings off, right in front of him. I drop them in the toilet, he's flipping out, and I just flush the rings down the toilet.
"I'm yelling at him, saying, 'Get out of my house!' "
Though Hank has denied the claims, Kendra - who has four-year-old son Hank Jr. and four-month-old daughter Alijah with the sportsman - is still unsure whether he is telling the truth and is convinced "something" happened.
Speaking to Giuliana Rancic on 'Beyond Candid With Giuliana: Kendra Wilkinson Baskett', she said: "Overall he was denying the whole thing. I don't know what to believe. Yes, I'm seriously mad at Hank because I know something happened. I've come very close to divorcing him already."
And the 29-year-old beauty hit out at "insulting" claims she and her spouse had invented the allegations to get publicity for her reality show.
She said: "I wish we did. It is the most insulting thing out of all this, that people think that this is fate. I would never do this to myself. You know, I would never degrade myself like that."

Lena Dunham was hospitalised after embarking on an extreme diet.
The 'Girls' creator resorted to desperate measures to lose weight ahead of the first season of the show but her shocking eating habits "messed" her up and left her with stomach pains.
She said: "I forced myself to attempt to rejigger (sic) my body. I couldn't even do it. I ended up hospitalised for drinking too much laxative tea and not taking care of myself.
"I had crazy stomach pains. It was basically revealed that I'd been just drinking laxative tea and coffee and smoking cigarettes and then eating weird foods at weird hours. I really messed myself up."
In her forthcoming new book, 'Not That Kind of Girl', Lena talked about the obsessive food journal she kept at the time and admits it was "painful" to address her problem in public.
She said: "My food intake was a hard thing to share publicly. A lot of my life and work is sort of about not succumbing to [those pressures], so it's a little painful to go, 'Oh but look, there was a time where this dominated every moment of every day.' "
And despite her past struggles, Lena, 28, insists she has changed her attitude to food, thanks in part to her "incredibly supportive boyfriend," Fun.'s Jack Antonoff, and is now content with her shape.
She told People magazine: "I really feel good with my size now. I know when I say that people are like, 'mm hmm', but I just do! It used to be when I went into a room with all thin women I felt like, what's wrong with me? Now I just feel special."

Paris Hilton and her friends ran up a bar bill of more than $230,000 on Wednesday night (24.09.14).
The hotel heiress - who is said to have earned $2.7 million from four nights of work on her recent two-month DJ tour - was partying at the Marquee club in New York with pals who ordered huge bottles of $100,000 Ace of Spades champagne.
The group also purchased 11 bottles each of Patrón, Cristal and Grey Goose but they were equally as generous to the club workers as they left a massive $47,000 tip at the end of the evening, according to the New York Post newspaper's Page Six column.
A source told the publication that Paris was "enjoying being the centre of attention" at the establishment.
But Paris' big night out is not her only huge spend of late after she splashed out $13,000 on a Pomeranian pooch, Prince, earlier this month.
The 33-year-old star has fallen in love with her cute canine - who is only 2.5 inches tall - and has already taken him for his first ever photoshoot.
What's more, the star's spending doesn't look likely to end there as she is searching for a home in New York.
Paris, who currently resides in Los Angeles, was recently shown around several plush pads in the Big Apple.
A source close to the socialite said: "Paris [is] looking at penthouse apartments downtown so she can be closer to her sister Nicky, who lives in New York, and her brother Barron, who also lives here."

'Bill & Ted 3' will feature multiple versions of the film's titular characters.
Alex Winter - the actor and filmmaker who played Bill S Preston alongside Keanu Reeves as Ted Theodore Logan in the earlier films - explained the third movie will start with Bill and Ted in their 40s.
He told Yahoo! Movies UK: "It fits very neatly in the [series]. It's not going to feel like a reboot.
"The conceit is really funny: what if you're middle-aged, haven't really grown up and you're supposed to have saved the world and maybe, just maybe, you kinda haven't?"
The 49-year-old actor explained that by including multiple versions of the main characters in the new film, the audience gains an insight into what they've been doing between the second and third movies.
He added: "[It's] answering the question: 'What happened to these guys?'
"They're supposed to have done all this stuff, they weren't the brightest bulbs on the tree, what happened 20 years later? To answer that question in a comedic way felt rich with possibility."
He said, too, that the original screenwriters Chris Matheson and Ed Solomon, as well as Keanu Reeves and himself have been the guiding influences behind the sequel.

The cast of 'Pride and Prejudice and Zombies' spent several days learning how to use a sword for their roles in the film.
The star-studded cast - which includes Suki Waterhouse - of the adaptation of Seth Grahame-Smith's parody of Jane Austen's classic novel were all shown the skills needed to kill zombies.
The actress-model - who is currently dating Hollywood superstar Bradley Cooper - told the Daily Mail newspaper: "We have to know how to kill zombies. You can't just give them a little shove."
Suki, 22, explained that much of Austen's prose will be kept in the film, which will also feature 'Downton Abbey' star Lily James, who will play the role of Elizabeth Bennet.
Suki said: "The zombie stuff is woven through the original text."
The actress appears well suited to the film as she already knows how to box and her father, a black belt, allowed her to attend karate classes when she was younger.
Earlier this month, it was also revealed former 'Doctor Who' star Matt Smith has been cast in the film.
Smith, 31, will play the role of a parson who proposes marriage to Elizabeth.
'Pride and Prejudice and Zombies' is set for release in 2015.

Chris Brown is "having fun" with Rihanna.
The 'Fine China' singer - who has an on/off relationship with model Karrueche Tran - has stayed close to his former girlfriend, who he was convicted of assaulting in 2009, but insists they are just friends.
He said: "We're friends. Nothing too serious... We're not trying to start a life together right now, we're just having fun."
Fans have speculated that 'Drunk Texting', a track on the 25-year-old star's new album 'X', is about Rihanna, and while Chris insists it isn't, he doesn't mind theories being shared because he thinks it encourages record sales.
Asked if the track is about Rihanna, he said in an interview on US TV show 'Entertainment Tonight': "Oh no, not at all. I think that's just the fans' perception or the media's perception at all times because of our history. But whenever we do music, people can make the assumption and that's fine because if they buy more because they think that, then go ahead and buy a thousand copies.
"But as far as me writing and going into that, I don't really try to put my focus on Rihanna every song. At the end of the day it's almost six, seven years later. It's like, how many more times am I going to talk about the same situation?"
Chris - who spent 108 days behind bars for violating his probation when he allegedly made threats about using guns while seeking anger-management treatment in rehab earlier this year - says he has become a more "humble" person in recent months and has finally moved past his shocking attack on his former girlfriend by forgiving himself.
He said: "You have to forgive yourself. You can't beat yourself up over the years, because it'll just eat at you and you'll be stuck in the past. And for me, I just learned to be a more humble individual and more of a conscious person."

Sofia Vergara thinks Joe Manganiello is "very hot".
The 'Modern Family' actress is smitten with the 'Magic Mike' actor - who she has been dating for almost three months - and says his most important quality is his ability to have fun.
Speaking on 'Live! With Kelly and Michael', she told hosts Kelly Ripa and Michael Strahan: "Well, he's very hot. He's a great guy, he's very funny. And he's very entertaining which is very important for me because I need to be with somebody that knows how to have fun because I like to have fun."
Kelly praised the couple as perfect and joked: "If I were you, I would put mirrors everywhere...I'd be like, 'Let's just look at ourselves right now.' "
Sofia replied: "Yeah that's all we do. When we're hanging out, we don't watch TV, we just watch ourselves."
The 43-year-old presenter then suggested the pair cover themselves in cake and look at each other, prompting the 42-year-old beauty to poke fun at her curvaceous frame.
She quipped: "He cannot eat that much cake. I eat it for him, because he's training."
And Sofia went on to confess to an "addiction" to cake, admitting she needs a sweet treat wherever she goes.
She admitted: "I'm addicted to cake. I have it in my house. I travel with it.
It's not carbohydrates, it's cake. I tried a gluten-free cake. I didn't like, but I still ate it."
And asked what food she would take to a desert island, she said: "[Cake]. It makes me happy ... If I'm sad I eat cake. If I'm happy, I eat cake."

Jessie J had to sell her glass house because of fame.
The 26-year-old singer was forced to sell her home in Surrey, south east England, after fans started to flock outside her plush pad in a desperate attempt to catch a glimpse of the star following her two series stint as a coach on talent show 'The Voice'.
She said: "I bought a house in Surrey. It was all made of glass.
"But after 'The Voice' I had a new, weird level of fame and I had to sell it as I couldn't be famous and live in a glass house."
Jessie admits she has a degree of sympathy for the new owners when she spotted a group of supporters outside the home singing her 2011 hit 'Domino', after she had moved out of the abode.
Speaking on tonight's (26.09.14) episode of chat show 'Alan Carr: Chatty Man', she added: "Six months after I sold, these kids were outside singing 'Domino'.
"I felt so sorry for the people who bought it."
While the raven-haired star has a huge fan base in the UK, she recently revealed she was planning to move to Los Angeles after selling her London home because she feels more "appreciated" across the pond.
She said: "In America they see me as a singer whereas here I feel that people don't appreciate my voice. I've dedicated my life to singing and I want it to be taken seriously.
"Here it seems that all people want to know is what I've had for breakfast and who I'm sleeping with."

Lady Gaga asked for her jacket back when audience members fought over it during a concert this week.
The 'Poker Face' hitmaker had tossed the neon garment into the crowd during her 'ArtRave: The ArtPop Ball' show in Antwerp, Belgium but was unhappy when two fans began fighting over the item of clothing in an attempt to take home a special memento of the gig.
She warned: "Careful. Don't fight."
Then, she sternly added: "Hey, hey. Give it back."
The audience gasped as they realised she was serious and the jacket was quickly returned.
Gaga handed the jacket to one of her dancers and told the crowd at the sold-out Sportpaleis venue: "If you're going to fight, you don't get to keep it. Here we practice love."
She then walked over to the fans who had been fighting, blew a kiss and said: "And don't worry, I still love you."
Gaga recently admitted she is overwhelmed by her success and the support of her fans, who she calls her Little Monsters.
She tweeted: "Spent a lot of time crying today, happy tears, but many. I can't believe my life. Being able to buy nice things, travel, it's overwhelming.
"Some days it hits me so hard, reality, I can't express my gratitude enough to monsters+team for believing in me. U changed my families life. (sic)"
The 'Born This Way' hitmaker admitted she is feeling "very humbled" at the moment and has vowed to continue to keep paying her supporters back by producing plenty of music and performing gigs.
She wrote: "I hope with my music, shows, and message I can share with you all these blessings though the beauty of art. Love, a very humbled Lady. (sic)"
