EastEnders' Phil Mitchell is to cheat on Sharon Rickman.
The Walford hardman will bed former flame Shirley Carter (Linda Henry) in coming weeks behind his fiancée's back - despite trying to move their wedding to an earlier date.
Phil (Steve McFadden) and Shirley will give into their feelings for each other and arrange secret sex sessions around Albert Square. The pair, who had an on/off relationship for years, are both privy to big secrets about each other and Shirley recently admitted she still loves Phil.
A source told the Daily Star newspaper: "Shirley and Phil know everything about each other, good and bad, it's part of their attraction. They feel like they can be themselves with each other.
"Add to that, they are both protecting each other. Phil knows Shirley is really Mick Carter's mum and Shirley knows Phil ordered the attack on The Albert that put Sharon in hospital.
"Now they are having an affair - another lie they are sharing. But how long can they keep it?"
While Phil attempts to juggle romances with both Shirley and Sharon (Letitia Dean), his bar owner fiancée is secretly plotting his downfall after discovering he had her beaten up in May.
Sharon has concocted an elaborate plan to steal all of Phil's money and enlisted the mechanic's former solicitor, the shady Marcus Christie, to help her.

Richard Madeley believes sex is the key to his happy marriage to Judy Finnigan.
The former 'This Morning' presenter has been married to his co-star wife, Judy, 65, for 28 years and credits their busy sex life for keeping their relationship going strong.
He told blinkbox Books: "I think relationships can evolve to a point in old age where sex becomes less important but I'm 58 not 98.
"In most dynamic marriages sex is a very important component. You can deny that at your peril. One of the reasons that most marriages fail is because there is growing sexual incompatibility. Research shows most happily married people in the '70s and '80s still have a functioning sex life and they should."
Meanwhile, Richard - who recently published his second book 'The Way You Look Tonight' - also revealed he wouldn't shy away from writing a raunchy novel similar to E.L. James' 'Fifty Shades of Grey'.
He said: "I really like writing about women. That is probably from doing 13 years on 'This Morning' which has a 60 to 70 per cent [female] audience. So much was clearly angled towards sexuality.
"You couldn't help over 13 years as a bloke to pick up on all kinds of aspects of what it is to be a woman today."

Kimberly Kisselovich suffered an ectopic pregnancy after having sex in the 'Big Brother' house.
The Playboy model shocked viewers of the Channel 5 reality show when she had sex with fellow housemate Steven Goode on national television, and now Kimberly has admitted she did fall pregnant following her on-screen session between the sheets but she has since lost the baby due to medical complications.
The 23-year-old beauty revealed that the "condom split" after their love making, resulting in an ectopic pregnancy, which is when a fertilised egg starts to develop outside of the womb.
Speaking to the Daily Star newspaper, Kimberly explained: "In the past 24 hours I've had a diagnosis from the doctor and he's sure that I have had an ectopic pregnancy.
"The doctor said that with the time frame it was definitely Steven's."
Kimberly was forced to leave the 'Big Brother' house after falling ill and was made to stay in hospital for four days, and she has admitted her ectopic pregnancy was the reason behind her quick exit from the show.
She added: "That's why I had so much pain in my pelvic area which I thought was an infection."
Kimberly could potentially face surgery to remove the egg from her fallopian tube and has admitted that she worries about her chances of having a baby in the future.
She said: "I'm really concerned. Steven's speaking to all the doctors - he's really upset.
"The doctor has said there's a chance I won't be able to have children. I'm trying to keep positive because we don't know for certain."
The NHS estimates that almost 11,000 women suffer an ectopic pregnancy every year, with approximately 65 per cent of women successfully falling pregnant within 18 months.

Jeff Bridges can't decide whether to relax or work harder as he is getting older.
The 64-year-old actor worries his time is running out so thinks he needs to cram in as much as possible, but has a conflicting feeling that he doesn't want to end his days by doing "homework".
He said: "I've got two conversations going on in my head. One says, 'Hey, you've got a lot of stuff you want to do, man. Now's the time, because you're gonna kick the bucket pretty soon.'
"The other says, 'Oh, Jeff, you want to make the rest of your life a giant homework assignment? Just relax, man. Just relax.' "
The 'Giver' star insists getting old doesn't worry him too much.
He added: "You inhale, you exhale, and you get on with it."
And one benefit Jeff - who has daughters Isabelle, 32, Jessie, 31, and Hayley, 28, with wife Susan Geston - has found that comes as time passes by is how much better marriage life has got.
He said: "What they don't tell you about marriage is that it just keeps getting better on all levels -- emotion, sex, intimacy. Intimacy is what we're all looking for. It's kind of a big high."
The 'Big Lebowski' star also recalled his "pretty great" upbringing with his wonderful parents, actors Dorothy and Lloyd Bridges.
Speaking to the August/September issue of AARP The Magazine, he said: "I had a pretty great childhood. [My mother] was kind of a spectacular mom.
"[My dad] had such tremendous fun with what he was doing, and the feeling was contagious."

Robert Pattinson "likes" his feelings of anxiety.
The 28-year-old actor has considered seeing a therapist but doesn't know how helpful it would be, and feels lucky his bouts of feeling low never last very long.
He joked: "I would love to go into therapy but it makes me too anxious."
He then added to The Daily Telegraph newspaper: "I've been talking to a lot of people about it and I don't know. I kind of like my anxiety in a funny sort of way and I like my peaks and troughs.
"Luckily, depression never lasts long with me."
The British actor saw his career skyrocket when he was cast as vampire Edward Cullen in the 'Twilight Saga' franchise and he admits he initially "struggled" with how fame changed his life, but is now more accepting.
He said: "I had a bit of a struggle at first because my life really contracted and I couldn't do a lot of the stuff I used to be able to do.
"But once I got through that a year or two ago I just accepted my life is something else and now I can't really remember what it was like before. So it's much easier to deal with."

Kelly Osbourne has been accused of letting her dogs poop all over her apartment.
The 'Fashion Police' host has taken legal action against her former West Hollywood landlord for keeping her security deposit when she moved out of the upmarket building, but he has now fired back and is suing her for damages caused to the property, TMZ reports.
Arshia Refoua insists he was right to keep Kelly's $18,700 deposit when she moved out in April 2013 because of the state she left the property in.
He alleges that, upon inspection, the apartment had holes in the walls, the hardwood floors were destroyed and there was dog urine and faeces "everywhere".
He also claims she caused extensive damage to the apartment after leaving the bathtub running, flooding both her property and ones below her.
The landlord is seeking damages of $50,000.
In her own lawsuit, as well as seeking the return of her deposit - which, under Californian law, would be doubled if the landlord is found to have wrongly retained it - Kelly asked for punitive damages because she was unhappy at having been branded a "filthy slob".
The 29-year-old star claims the landlord never bothered to stop by and check the property when she was moving out, but shortly afterwards received an email claiming the full deposit was required to cover damage and cleaning expenses.

Jason Derulo has praised Robin Thicke's "desperate" attempts to win back Paula Patton.
The 24-year-old star admits he isn't exactly "best of friends" with the 'Blurred Lines' hitmaker but he sympathises with him for trying to get his estranged wife - with who he has four-year-old son Julian - back by penning his latest album 'Paula' in her honour.
He said: "I think when somebody's desperate, they're desperate.
"I can't knock him for trying. He's trying everything to get his girl back, so I can't knock him for that ... I talked to him personally, and we're not necessarily like the best of friends or anything, but you know, he mentioned something about that.
"So you can tell when somebody is in dire need of having that special person back. And I think that's all it is."
Jason doesn't think there is anything wrong with Robin - who split from Paula earlier this year after eight years of marriage - talking about his feelings for the actress openly because as a singer/songwriter he is naturally a "creative" person.
Speaking to E!, he added: "As a musician, as a songwriter, that's what we do. We put our hearts on our sleeves and what's ever on our mind we just go to our safe zone, which is writing songs.
"So it seems to me that it's right in line with what a creative person would actually do. I think if he wasn't creative, then he wouldn't be talking about it all but the fact that he's a creative guy, that's what's on his mind and that's what he's going to talk about."

Jake Bugg is already working on his third album and has 10 to 15 songs saved on his iPhone.
Although the 'Lightning Bolt' singer only released his second record 'Shangri La' in October, he is already hard at work on new music but won't let anyone hear it yet.
Insisting that the songs are not yet completed, he told NME magazine: "I've been trying to keep what I'm doing under wraps at the minute. A producer or someone could stick me on the mics and I'll just make something up on the spot and not share the ideas that I've actually spent a bit of time on because I just want to have a bit more time with it."
However, he has been asking producer Rick Rubin for advice.
He explained: "I show him ideas and keep him updated with what I'm doing, because he's a great guy and his advice is always great to hear."
Jake loved working with Rick, who has recorded with the likes of Ed Sheeran, Kanye West and Eminem, on his second record.
He previously explained: "Despite if I knew him or not, I had enough people telling me the reputation he had, so I just didn't think it was an opportunity to turn your nose up at.
"You might learn something, you might get something out of it, you might not, but you'll definitely learn something.
"The experience as a whole was great, he brought in great musicians. I just had a load of ideas, and I'd sit down and teach the band. He'd drag those ideas out of me and make sure I turn them into songs.
"It was just pretty relaxed, we'd record a song four or five times and then onto the next. Pretty easy."

Diplo has revealed his first single with Skrillex will be called 'Take You There', and says the pair are working on a mixtape together.
The track features vocals from Kiesza with Diplo revealing during a Reddit Ask Me Anything [AMA] session that he hopes to release it this week.
He said: "[I] wanna try and get a stream out it out this week."
And Diplo confirmed that the pair are "doing a mixtape" as part of their 'Jack U' collaboration which they have been teasing fans about for months.
Meanwhile, Diplo recently revealed that he and Madonna are collaborating on her new album.
He said: "We've written about seven songs now, and hopefully maybe four or five will make it to the album. I've done about three weeks with her, and we're gonna do some more projects at the end of July. She's just really cool. I think as far as artists reinventing themselves, she did it before anybody else. She kind of began that trend of actually coming back with a whole new look and style and sound and winning it and hitting the top of the charts. Those records are gonna be crazy-sounding. We really pushed the envelope with some of the stuff we were doing."

Alex Kurtzman could be set to direct a reboot of 'The Mummy'.
The 40-year-old director - whose writing credits include 'The Legend of Zorro' and 'Cowboys and Aliens' - has already been confirmed as the film's producer, alongside Chris Morgan.
Jeff Kirschenbaum, co-president of production at Universal Pictures, told The Hollywood Reporter: "Over the course of developing 'The Mummy', Alex has demonstrated such clarity and passion about this character and mythology.
"He knows why 'The Mummy' has fascinated us for so long and how to bring that into an inventive, incredible new adventure. It became obvious that he is the perfect choice to be not only one of the narrative engineers of this new vision but its director as well."
Len Wiseman and Andy Muschietti were previously attached to direct the film while Sean Daniel and Bobby Cohen have been handed producing roles.
Details of the script remain a closely-guarded secret, but it's been revealed that the remake will be set in the present day and will take on an action-adventure genre rather than a horror and will feature entirely new characters.
'The Mummy' is to be the first of a series of Universal film franchises scheduled to undergo a reboot, with the studio announcing an April 2016 release date.

James Buckley acquired a taste for kangaroo meat while filming 'The Inbetweeners 2'.
The 26-year-old actor - who stars as compulsive liar and supposed ladies man Jay Cartwright in the comedy series - has revealed that when he reunited with co-stars Simon Bird, Joe Thomas and Blake Harrison in the Australian outback for the filming of the sequel, they all gave the local cuisine a go.
He explained: "That is the type of place it was. If they didn't have kangaroo meat in the freezer, they'd go out and shoot and then that would be food for the next couple of weeks or whatever, however much they can get out of kangaroo.
"So now I love kangaroo. It was good having teriyaki kangaroo at a Japanese restaurant there. It was nice."
Meanwhile, Thomas - who plays hopeless romantic Simon Cooper - claimed they had to get back together for a sequel, following on from the success of the first movie and the original TV series, because they don't have any other friends.
He told the Daily Mirror newspaper: "It was nice to come back to do this show because I think we had all sort of gone away and tried to do other things ... And we don't really have other friends. We've just got each other! So, yeah, it was good, it was really great to come back."
'The Inbetweeners 2' is to be released in the United Kingdom on August 6.
