Demi and Ashton: Inside their split

As Ashton Kutcher is hit with cheating claims and Demi Moore wastes away, the superstar couple are reported to be calling it quits.

On the eve of their six-year wedding anniversary, Demi Moore and Ashton Kutcher hardly looked like a happily married couple. While the increasingly frail-looking actress attended a Beverly Hills event alone, her young husband partied up a storm in San Diego on September 23, flirting with several scantily clad women at Fluxx nightclub. According to US magazine Star, Ashton later enjoyed a liaison with blonde student Sara Leal, who is thought to have DNA evidence of their affair.

It’s this alleged infidelity that has reportedly caused Demi to call an end to their marriage – previously thought to be one of Hollywood’s strongest, despite their 15-year age gap – after months of leading separate lives. “It was definitely a long time coming, but they’re finally done for good,” claims a family insider in Star. “Ashton was a serial cheater, and she just couldn’t take it any more. It’s a painful time for Demi.” And it shows. The 48-year-old actress – who has previously admitted to an “extreme obsession” with her body – has shocked friends and fans with a string of scarily skinny appearances at recent red carpet events. Woman’s Day can reveal Demi’s weight has plummeted to just 45kgs after two weeks on a brutal detox, during which she consumed little more than lemon juice and maple syrup.

The dramatic body overhaul is seen as a desperate attempt to win back the affections of her much-younger husband, as his star rises with a highly paid role on the revamped ratings-winner Two And A Half Men. However, Demi’s drastic diet has clearly not paid off. She appears to have aged overnight and lost Ashton. Star magazine reports that 33-year-old Ashton brought blonde student Sara back to his room at the Hard Rock Hotel, telling the beautiful 20-something that he and his wife were “separated, but the public just doesn’t know yet”. This comes almost exactly a year after 22-year-old Brittney Jones claimed she had slept with Ashton on his and Demi’s couch while Demi was out of town.

She told the press she believed the stars had an open marriage and confessed to swapping a string of steamy texts with Ashton until he told her, “For now, I don’t think I should be talking to any girl that’s not my wife.” The couple denied the story at the time. There have been rumours of Ashton’s wandering eye ever since he and Demi tied the knot in a traditional Kabbalah ceremony in 2005 and, according to Star magazine, the couple gradually gave up hope on saving their love.
