Ashton Kutcher's recent sex scandal in San Diego with Sara Leal was the final blow to his six year marriage, but as Star magazine was the first to reveal, it was not the first time he had been caught cheating.

As Star exclusively revealed, Brittney Jones had a salacious, short-lived affair with the married man last year and is now speaking out about their sexual escapades.

Brittney met Ashton in July 2010 at the Lucky Strike Lanes in Hollywood, when he was bowling with wife, Demi Moore, and the Two and a Half Men star was instantly infatuated with the pretty brunette.

Ashton Kutcher’s cheating on his wife was the straw that broke the camel’s back but it was the “open marriage” they had that was the downfall in their marriage.

Demi Moore, 49, is filing for divorce from her 33-year-old husband after his latest affair became public, and Star magazine has exclusively learned that her secret life with Ashton and their “open marriage” has been much more twisted than anyone imagined.

“Everyone in Hollywood knows about their arrangement, but they’ve managed to keep it a secret from the general public,” an insider said about the A-list couple.

In the wake of yet another cheating scandal, Demi Moore has had enough of her toy boy husband Ashton Kutcher's philandering and is ready to call it quits.

According to an exclusive report in Star Magazine, the May to December marriage is over because of Kutcher's infidelities and the couple have been living apart for some time.

Instead of celebrating his sixth wedding anniversary (which was on September 24), the new star of Two and A Half Men spent last Friday flirting with scantily-clad women at Fluxx nightclub in San Diego, the new issue of Star Magazine exclusively reveals, where he looked nothing like a happily-married man.

Actor Ashton Kutcher has listed his 3,235 square-foot home for sale online and RadarOnline.com has learned a chunk of the sale will be donated to the Demi and Ashton Foundation – a non-profit that raises awareness for child sex slavery and the rehabilitation of victims.

The woman who romped with Ashton Kutcher on the couch at his Hollywood mansion was in secret negotiations to star in a porn video, RadarOnline.com has exclusively learned.

What’s more, the brunette beauty had even secured a slice of the tape's total profits.

Brittney Jones -- the woman who claims she slept with actor Ashton Kutcher -- has put a sweater on eBay, claiming it belongs to the That 70s Show heartthrob.
