“Demi Moore is bisexual and had an open marriage with Ashton Kutcher”, Star revealed.

As Demi Moore has officially announced she is ending her six year marriage to Ashton Kutcher after reports of his alleged infidelities became public, the couple’s issues seem to have been a lot more complex.

It is believed Demi Moore, 49, and Ashton Kutcher, 33, embarked on an “open marriage”, with suggestions hinting that the actress is bisexual.

An insider told Star: “Demi is attracted to women just as much as men, so she didn’t always get all she needed from Ashton.”

Speaking of Demi Moore and Ashton Kutcher’s agreement to have an open marriage, the source added: “Everyone in Hollywood knows about their arrangement, but they’ve managed to keep it a secret from the general public.

“She was cool with Ashton having flirtatious relationships too. Somehow they made it work all these years. Both of them were respectful of each other. It was a lot of fun for them.”

However, it all changed when Ashton Kutcher’s alleged affairs became public and it seems their liberal outlook soon turned sour.

Comedienne Chelsea Handler seemed to echo the sentiments, speaking to Piers Morgan on CNN.

While Chelsea Handler admitted she didn’t know Demi Moore and Ashton Kutcher well personally, she said: “I think it’s pretty obvious that they’ve probably had a lot of open marriage type situations.

“I think they probably had a lot of good times with some other women… Clearly they had a lot of threesomes, that led to twosomes without Demi and that leads to a divorce. I absolutely feel for her.”

Brittney Jones, Ashton Kutcher’s first alleged mistress, who came forward with the affair story in September 2010, insisted at the time that the actor had an “open marriage” with his wife.

At the time, Brittney Jones’ credibility was quashed by Ashton Kutcher’s lawyer who insinuated she was lying.

Yet today, Brittney Jones told TMZ: “Although divorce is often sad I do feel somewhat vindicated.

“For so long people have thought that I was dishonest or just making up my passionate nights with Ashton, when in fact I was being used.

“Ashton told me that both he and Demi had an <<open relationship>> and that he was not in fact cheating.

“Now I can tell all the facts about how Ashton really was, and hopefully people will believe my side of the story.”

Demi Moore said in a statement today that she is filing for divorce with “great sadness and a heavy heart”.
