Kelly Osbourne thinks it is "insane" someone has paid $20,000 to have dinner with her family.
The showbiz clan - rocker Ozzy Osbourne, his wife Sharon and their children Jack and Kelly - donated a family meal for an auction at the Race to Erase MS gala event at the weekend, and the 'Fashion Police' host can't believe how much their lot raised for the multiple sclerosis (MS) charity.
Kelly wrote on her blog: "Can you believe that someone bid $20,000 to have dinner with my family???? That's insane but thank you thank you thank you whomever you are, I can't wait to have dinner with you!!!!! It's going to be a fun one so get prepared... YOU HAVE BEEN WARNED!!!! (sic)"
Kelly herself also got involved with the auction, winning a bidding war against her brother - who suffers from MS - for a vacation in Mexico, for which she paid $6,000.
A bespoke Aston Martin Vanquish - which was commissioned by the Osbourne family - attracted the highest bid of the night, selling for $230,000.
As well as the auction, which was hosted by Jack and Howie Mandel, guests at the Hyatt Regency Century Plaza hotel in Los Angeles were entertained with performances by Steven Tyler, Cee Lo Green and Natalie Cole, while Jordin Sparks was among the speakers.
The annual event raised $1.75 million dollars for Race to Erase MS and its Center Without Walls programme, a collaboration of top MS research centres working together as a team on ground-breaking research to treat and ultimately find a cure for the disease.

Justin Timberlake loves trying new things.
The 33-year-old singer and actor believes it is important to learn from everything he does, so knows if he starts to repeat himself, it's time to do something different.
Speaking on the new season of 'Oprah's Master Class', he said: "If I'm not learning from something that I'm doing, then that means I've done it before. Do something different, even if it's within the same medium.
"To try new things, that makes more sense to me than making a career out of doing the exact same thing over and over and over and over again."
And the 'Mirrors' hitmaker - who is married to Jessica Biel - feels particularly excited and inspired when he embarks on a new challenge that takes him out of his comfort zone.
He added: "I like the moment where I can look at everyone and say, 'I have no idea how to do this. Let's figure it out.'
You do that with a stage performance as much as you do a character on film. That inspires me. That motivates me."
Other stars who will appear on the new season of 'Oprah's Master Class' include singer Lionel Ritchie, actresses Whoopi Goldberg and Sharon Stone, and 'Fargo' star Billy Bob Thornton.

Jon Hamm admits working on porn movies was "soul-crushing".
The 'Mad Men' actor was a set-dresser on softcore adult movies in the late 1990s and says it was one of the worst jobs he'd ever had.
Discussing a recently resurfaced episode of 'The Big Date', which he appeared on in 1996, he said: "I was actually at that time working as a set dresser for Cinemax soft-core-porn movies. It was soul-crushing."
Jon's career has come on massively in recent years and he doesn't think he'll ever get a better job than playing advertising boss Don Draper in 'Mad Men', which will come to an end after its current seventh season.
Speaking to the new issue of Vanity Fair magazine, he said: "This is the best job I've ever had and maybe ever will have in my life--it's so fun to play all of this. It can be relentlessly dark. It can be terribly sexually inappropriate, is a way to say it. But who else gets a chance to do any of that stuff? There's so much there."
Jon is also heavily involved with the plotlines of the drama, with show creator Matthew Weiner admitting he knows "everything" that is going to happen and the writers often go to the actor for suggestions when they get "stuck".
Matthew said: "He knows everything. He's the first, outside the writers' room. I try stuff out on him.
"When we get stuck in the writers' room, I go down there and have a conversation with him."

Arctic Monkeys have defended claims all of their shows are a "routine".
The 'Snap Out Of It' band were slammed by American act The Orwells - who supported them on their US tour and claim they play the same show every night - while frontman Alex Turner uses the same ad-libs on stage.
Guitarist Matt O'Keefe told Gigwise: "When you're playing arenas and everything, it's a huge production then the show has to become synchronised to work.
"So every night no matter how he [Alex] was feeling he'd go into that opening riff. It was the exact same ad-libs he was putting between songs. So we were with them for about 50 dates, you saw them once you'd pretty much seen every date they'd played."
Alex, 28, has responded to the claim and thinks it "isn't fair" to call the shows "synchronised" just because the set has structure.
Talking about The Orwells, he told News Limited: "They should have been out trying to get laid instead of watching us every night.
"There comes a time on a tour when something works and you tend to leave it alone. We have been changing it around a little bit. You can't mess around with it too much. It's almost like the show isn't designed to be watched by the same person every night.
"Nowadays people share the set lists, but I'm by no means f***ing phoning it in. It's not like we have (pre-recorded) tracks we're up there f***ing doing it."
Meanwhile, Arctic Moneys - also made up of drummer Matt Helders, guitarist Jamie Cook and bassist Nick O'Malley - will kick off their biggest Australian tour in Sydney tonight (06.05.14).

Rihanna is preparing to release her next album with Roc Nation after leaving Def Jam.
The 'Diamonds' singer, who was already being managed by Jay Z's record label, has now inked a deal and her profile on Roc Nation's website has been updated, which lists her as one of their big name acts.
Rihanna first signed her record deal with Def Jam in 2005, when she was just 17, and claims then-label-president Jay Z wouldn't let her out of his office until she put pen to paper.
Since then, she has released all seven of her chart conquering albums with the label, including 2011's 'Unapologetic', despite Jay Z leaving his role to start up Roc Nation in 2009.
Rihanna had already parted ways with her former manager Marc Jordan and signed with Jay's Roc Nation management team in 2010 but it now appears she is also signed to the label.
She joins the likes of Calvin Harris, DJ Mustard, J. Cole, Jay Electronica, Rita Ora and Jay Z himself.
Meanwhile, the Def Jam website now lists Rihanna under its "Legacy" section, along with stars like Amerie, Ashanti, and Public Enemy.
The 26-year-old star will release her next album "soon" and will be spending more time in the studio than taking 'selfies' after her Instagram account was suspended for posting half-naked photographs.

Ed Sheeran performed new material at a secret gig in London yesterday (05.05.14).
The 'Drunk' hitmaker took to the stage at Koko in Camden to play songs from his second album 'x' and fans packed into the 1,500-capacity venue after scrambling to get tickets.
Dressed in his usual low-key attire, the star wore a red t-shirt, black jeans and combat boots and wowed the crowd with his rap skills during an extended version of 'You Need Me (I Don't Need You)', before performing his hit 'Lego House'.
Fans already knew the lyrics to new track 'Don't', about a singer who cheated on Ed in a hotel room with his friend.
Girls in the back of the venue whispered about reports it is written about Ellie Goulding but Ed kept quiet on the subject matter.
The singer-songwriter went on to perform hits 'Drunk, 'Gimme Love' and ' I See Fire' from 'The Hobbit: The Desolation of Smaug', along with new ballad 'Tenerife Sea', a stunning love song written at the Grammys.
He explained how he went to the ceremony with his parents and felt out of place. The song's honest lyrics make it one of the best tracks he's played so far from the new record.
Ed spoke to the crowd in hushed tones and got fans to quietly sing along, before whipping them into a frenzy with his impressive falsetto, harmonies and rap beats layered with a new loop pedal.
"I want you to act as if it's a festival Sunday", he told the crowd, after thanking them for giving up their bank holiday to watch him play.
He slowed things down again with 'One' and 'The A-Team', which still never fails to bring tears to your eyes, before bowing out with 'Sing', his up tempo new single produced by Pharrell Williams, which had the crowd singing the track's riff on repeat until the lights came up, and no doubt until the next morning.
The concert was the second of three secret 'Multipy' gigs after he performed at a pub in Ipswich and later headed to Dublin.

Ade Edmondson believes panel shows are stunting creativity in comedy.
The 57-year-old comic made his name in the 80s with his alternative stand-up show with Rik Mayall and then as one of the main stars of offbeat and satirical sitcom 'The Young Ones' - famous for its political and surreal humour.
Ade thinks there are too many comedy panel series on TV now and these easy to make programmes are stopping more interesting comedic shows from being made.
He told BANG Showbiz: "There's a point where I watch comedy and I think, 'Yeah I know that one.' I know the form, and it takes a lot to surprise me any more. I think it's been a long time since there's been a new comedy idea, I think it's the panel game format. There are some lovely versions of it; I love 'Have I Got News For You' and 'QI' and stuff like that but it's all the same level of thinking. It never really gets bizarre.
"The one good comic I've seen in the last year is Harry Hill. I went to see Harry live at The Apollo and that was still different and still surprising and funny. But it's hard because TV executives don't want to make interesting programmes, they just want to make panel shows which they can churn out."
Ade has done very little comedy since he stopped working with long-term writing and acting partner Rik in the early 200s.
The 'Celebrity Masterchef' winner - whose most recent acting role is in crime drama 'Prey' - doesn't think that's a situation that will change any time soon as he doesn't have the same appetite for the genre as he used to.
Ade - who has partnered with Merrydown cider to cook up three brand new recipes made from the alcoholic drink (Facebook.com/merrydown.cider) - said: "I'll be doing very little comedy I think. I'm not averse to little bits of it but I'm not chasing it like I used to because I don't feel that need, I don't even watch a lot of comedy any more - it doesn't excite me in the way it used to."

Dannii Minogue would love to return to 'Home and Away'.
The former 'X Factor' judge played Emma Jackson in the Australian soap from 1989 to 1990 before her character left Summer Bay to take a job as an air hostess, and she's now admitted she'd love to reprise her role and get back together with her former co-stars.
Speaking to TV Week, she said: "I'd love to get back on the 'Home and Away' set and have a revisit. I think anything is possible with the right scriptwriters. I think it would be fun.
"There are a few old friends there who were there when I was on, so it could be great."
Kate Richie - who spent 20 years on 'Home and Away' playing Sally Fletcher - added that she would also like to see Dannii back on 'Home and Away', and claimed she would even consider reprising her own role.
She said: "If they're brining Emma back, we'll have to do a double deal on that one. Maybe Sally could confront her. That would be fun!"
Meanwhile, 42-year-old Dannii - whose sister Kylie Minogue starred on rival soap 'Neighbours' in the '80s - has confessed she'd also like to make a cameo appearance in prison drama 'Wentworth'.
She said: "I would love to do 'Wentworth' - really. No make-up, a prison outfit, working the press and the bad Dannii would come back. Now that would interest me.
"Working in drama was such a big part of my teenage years and I always enjoyed it."

Julie Hesmondhalgh is to star in a new drama about modern homosexual life.
The 44-year-old actress has been cast alongside Freddie Fox and Vincent Franklin in Channel 4's upcoming eight-part series 'Cucumber' - which was first announced last year and is set in Manchester.
The programme will offer a glimpse into the "passions and pitfalls of 21st century gay life" and Julie will portray Cleo, the sister of Vincent's character Henry.
Other cast members include Cyril Nri, Fisayo Akinade, Con O'Neill, James Murray and Ceallach Spellman.
'Cucumber' - which is due to air in 2015 - is the new show from screenwriter Russell T Davies who was the creator of 1999 series 'Queer As Folk', which followed the lives of three homosexual men who lived in Manchester's gay village.
Davies was also responsible for bringing 'Doctor Who' back to television in 2005 after a 16-year absence from screens.
Channel 4 is also filming a companion series entitled 'Banana' which will air on E4 and feature the same characters.
'Cucumber' will be Julie's first TV role since she left 'Coronation Street' in January 2014 after playing transsexual factory worker Hayley Cropper for 15 years.
Her moving final scenes which showed Hayley take her own life after deciding she could no longer live with her terminal pancreatic cancer, passing away in the arms of her husband Roy Cropper (David Neilson), were watched by over 10 million viewers.

Emma Stone insists Gwen Stacy is Spider-Man's "equal".
The 25-year-old star plays Peter Parker's love interest in 'The Amazing Spider-Man 2' and believes her alter-ego is a "modern day" woman who can take control of her own future.
Talking to screenrant.com, she said: "They were pretty clear that that's what they wanted to--the kind of Gwen that they wanted. At my first audition, that she was going to be his equal and that she was going to be a modern woman.
"But I think especially in the second movie that point is really driven home because she is so willfully putting herself into these situations even though he wants to protect her and keep his distance from her. And she's also, you know her ambitions are strong and she's going off to school and she's carving out her own path with or without Peter."
Asked about whether the 'Wait here and let me protect you!' thing works, Stone replied: "It doesn't really fly with her. Especially when she gets webbed to a car, she's super p***ed."
Stone was delighted to be cast as Stacy for the original 2012 movie since it's an untold story and she was thrilled to reprise her role for the sequel.
She added: "A lot of people didn't know the Gwen Stacy story. I didn't know it before I auditioned to play her, so it was pretty cool being back in it."

Christopher Mintz-Plasse thinks Zac Efron's fans will be surprised by his performance in 'Bad Neighbours'.
The 24-year-old actor stars alongside the 'High School Musical' heartthrob in the upcoming comedy and has confessed he thinks Efron's fans will be surprised to see how well he suits the genre.
Quizzed on how his co-star Seth Rogen and producer Evan Goldberg pushed the boundaries in the film, Mintz-Plasse told Collider: "I think the biggest thing that they did in this, or the biggest stretch or biggest person, was Zac because this is the craziest thing he's ever done.
"Him swearing, making d**k jokes and having sex with girls on screen is the craziest thing he's ever done, and I think people are going to see it and at first they're going to be like, 'Oh, hey, it's Zac', and then I think they're going to realise how hilarious he is and how talented he is."
Mintz-Plasse - who is best known for playing McLovin' in 2007 hit comedy 'Superbad' - admitted that having seen the film, he can't imagine anyone else doing a better job than Efron.
He added: "He's great in this movie. No one else could have done it."

Kiefer Sutherland is dating Sofia Karstens.
The '24: Live Another Day' actor is said to have been spending a lot of time with the 37-year-old actress, including a recent trip to New York, and they are "really happy" with one another.
A source told People: "They are really happy together."
Kiefer was previously married to Camelia Kath - with who he has daughter Sarah and stepdaughter Michelle - and Elizabeth Kelly Winn, while Sofia married Jason London in 2011, but they filed for legal separation in February this year.
Kiefer recently reprised his role as former counter-terrorism agent Jack Bauer in '24' spin-off '24: Live Another Day' - which sees his character a fugitive living in the UK - and recently admitted filming left him "bruised and battered".
He said: "I was definitely bruised and battered this time around. Once, I went to open a metal door while being shot at and didn't realise it was a prop. I pulled the door handle off completely and fragments shattered in my face.
"Then a bullet cartridge firing multiple rounds freakishly hit a metal beam and bounced three inches from my face. I had blood pouring out. But, listen, I'd do anything for this character."
And though the actor is much older than when the show first started in 2001, he insists he is in better shape than ever.
He said: "I am older. There's no way around that. But I had the luxury of training for four or five months coming into this, and when we started, I was in the best shape of my life. That helped me bounce back faster."
