This is the latest development, according to reports, in the rumors surrounding the break-up of Hollywood couple Ashton Kutcher, 33 and Demi Moore, 48 - Kucher has begged his wife for forgiveness. The couple is believed to be going through a difficult time after Kutcher allegedly cheated on Moore with Sara Leal, 23. Kutcher allegedly cheated on Moore when he had unprotected sex with Leal, at a hot-tub party.

The couple is still, officially tight-lipped about the whole episode. Kutcher had to force a smile on his face, when posing with Jason Segal of How I Met Your Mother fame, at the Decade of Difference Concert at the Hollywood Bowl, according to a Daily Mail report.

There are also rumors of Moore having already consulted a divorce lawyer, along with other reports that say that Kutcher moved out of the couple's house, back in September, following his wife's increasing substance abuse problems. However, neither of these has been confirmed by any official source.

Leal recently gave an interview to US Weekly, where she revealed explicit details of her encounter with the star of popular television sitcom, Two And A Half Men. Leal spoke in detail about her alleged sexual encounter at a San Diego hotel and also told the tabloid that Kutcher told her he was separated from Moore. It is unclear if Leal was paid for the interview. However, a report in Page Six said that Leal was looking for a six-figure deal for her version of the events.

According to the report in the Daily Mail, Kutcher has persuaded his wife to delay filing for divorce, since the rating of his television show is dropping drastically. He reportedly told Moore that he deserves a second chance.

Demi's entire group of family, friends and co-workers are telling her to move on, the Mail quoted an industry insider as saying.

But she's a wreck - embarrassed and devastated about how she's been betrayed, but really torn, the source added.

While there is still no official response from the couple over the rumors of infidelity, there was a tweet from Kutcher that did look like an attempt to quell the rumors. It said, When you ASSUME to know that which you know nothing of you make an ASS out of U and ME.

This is the second time rumors have surfaced over Kutcher's fidelity to his wife. The first was when he reportedly had an affair with Brittney Jones, 22. Kutcher took strong exception to those rumors, threatening to sue The National Enquirer for publishing a story about them. However, there seemed to be no adverse impact on his marriage with Moore at that time.

Although Kutcher appeared depressed, he did spend time in the exclusive VIP area at the concert, which was organized to raise awareness of the Clinton Foundation's efforts to improve global health, strengthen economies worldwide, promote healthier childhoods and protect the environment.

He also took to the stage to talk about the foundation before singers like Stevie Wonder, Lady Gaga and Usher performed to a screaming crowd of thousands, the report said.
