Sometimes you might look over at your work husband or wife and think, 'Maybe we'd be a great couple outside of work?' But STOP! Work is work and when you take the work spouse out of the work world, it's a bit like trying to quit chocolate at Christmas - a bad idea that you've not properly thought through.
However, sometimes people have ill-advised ideas that are triggered by their lusty hormones at work and these celebrities all fell afoul of making work a little more play and sometimes taking their co-stars to a bedroom that wasn't their matrimonial one.
Angelina Jolie and Billy Bob Thornton
Her reputation as the ‘wild child’ of the ‘90s was cemented when Angelina Jolie, 49, embarked on her first affair with married actor Billy Bob Thornton, 69, on the set of 1999 film Pushing Tin. At the time, Billy Bob was engaged to Laura Dern, but swiftly ended their romance, tying the knot with Angelina in Las Vegas the following year.
Initially their romance raised eyebrows for their 20-year age difference, but later, speculation over the private details of their two-year marriage reached overdrive when the pair revealed how they had gathered a pinprick of blood from each other to keep in vials around their necks when they couldn’t be together.
Kristen Stewart and Rupert Sanders
Famously admitting there was ‘nothing [she] could do’ to stop herself falling in love with her Twilight co-star Robert Pattison, 39, Kristen Stewart made further headlines worldwide when she confessed that she and R-Patz loved to lick each other’s armpits in the bedroom.
However, their four year romance was doomed when Kristen, 35, began filming the lead role in Snow White and The Huntsman, in 2012 – engaging in a brief affair with married director Rupert Sanders.
After pictures of the pair kissing emerged, Rupert, 54, was forced to make a statement, saying, ‘I am utterly distraught about the pain I have caused my family. My beautiful wife and heavenly children are all I have in this world. I love them with all my heart. I am praying that we can get through this together.’
Meanwhile, model Liberty posted a picture of Disney princess Snow White to Twitter, writing, ‘Not so pretty or so pure after all’. The couple, who share two children, divorced a year later.
Tom Ellis and Emilie De Ravin
Vowing to remain friends with her ex-husband of seven years, Tom Ellis, weeks after their 2013 split, Tamsin Outhwaite soon changed her mind after learning of his affair with his Once Upon a Time co-star, Emilie de Ravin.
In 2013, the former EastEnders star, 54, who shares teens Florence and Marnie with Tom, 46, marked the 10th anniversary of their split, posting in a since-deleted tweet, ‘Ten years since the father of my kids walked out on us for the final time. I still meet new people on jobs who reveal more infidelities and lies that he committed.
‘But thankfully my heart and soul are clear and clean and I could not be happier right now.'
Ryan Phillipe and Abbie Cornish
Meeting at her 21st birthday party, Reese Witherspoon, now 49, and Ryan Phillippe, 50, – who she described as her ‘birthday present’ - went on to star in teen movie, Cruel Intentions, together in 1999 before marrying just a few weeks after the film was released.
The couple, who now co-parent daughter Ava and son Deacon, announced they were divorcing in 2006, just three months after Ryan began filming the movie Stop Less with young Australian actress Abbie Cornish.
Not appearing to hide his rumoured affair with Abbie, Ryan later admitted, ‘I don't think an outside person can ever cause a divorce. I had difficulties in my relationship, and in my marriage, long before I ever met her.’ He didn’t, however, clarify that his marriage had actually ended before they embarked on their three year relationship.
Johnny Depp and Amber Heard
Johnny Depp, 61, and Amber Heard’s defamation trial three years ago unveiled a litany of fiery fights, alleged drug misuse and alleged violence during their seven-year relationship – making clear that their rocky romance had resulted in as much pain as their initial affair.
At the time they met on the set of The Rum Diaries in 2009, Johnny had been with model and actress Vanessa Paradis for 14 years before their eventual 2012 split.
On meeting Amber, 39, who had also been in a relationship with photographer Tasya van Ree, on set, Johnny later confessed that he had developed feelings for her during a steamy shower scene, which eventually led to kissing and wine off-set.
LeAnn Rimes and Eddie Cibrian
LeAnn Rimes first began Dancing in the Moonlight with husband Eddie Cibrian when the pair embarked on an affair after meeting on the set of Northern Lights back in 2008.
LeAnn, 42 was married to Dean Sheremet while Eddie, 51, was married to Brandi Glanville, with the pair both divorcing their respective partners before marrying in 2011.
A year before their wedding, LeAnn spoke candidly about their affair, saying, ‘I did one of the most selfish things that I possibly could do, in hurting someone else. I take responsibility for everything I've done. I hate that people got hurt, but I don't regret the outcome.’
Kenneth Branagh and Helena Bonham Carter
Actors Kenneth Branagh, 64, and Helena Bonham Carter, 58, embarked on an affair when they met on the set of Frankenstein in 1995, while he was still married to all-time English sweetheart Emma Thompson, 66.
Reflecting on when she first learnt of the affair, Emma later admitted, ‘I was utterly, utterly blind to the fact that he had relationships with other women on set. ‘…I was half alive. Any sense of being a lovable or worthy person had gone completely.’
She did, however, channel her heartbreak into her amazing role as wronged wife, Karen, in 2003 romance, Love Actually.
Tom Cruise and Nicole Kidman
While famous exes Tom Cruise, 62, and Nicole Kidman, 57, have never confirmed that they embarked in an affair, Nicole has admitted her ‘jaw dropped’ when she first laid eyes on future-husband Tom when she co-starred as his love interest in 1990 flick, Days of Thunder.
During filming intimate scenes with Nicole, Tom had been married to Mimi Rogers. The couple are believed to have unofficially split the previous year, but with the divorce seemingly sped up, Tom was free to marry Nicole just ten months later.
The couple adopted two children together before Tom filed for divorce in 2001, leaving Nicole ‘in shock’.
