So what exactly is going on here?

There is no putting a full stop to the rumors about the possible break-up of Hollywood couple Ashton Kutcher and Demi Moore's marriage. The two have not commented on the matter so far, leaving their fans speculating.

Kutcher's alleged cheating on Moore with Sara Leal, 22, is reportedly taking a toll on Moore's health. However, the couple seems determined to save their marriage.

A report from US Weekly indicates that Moore, 48, showed up on the sets of sitcom Two and a Half Men, on Friday, to visit Kutcher, 33, who was due to shoot some hot and heavy scenes.

Demi didn't come on the actual shooting set or anything -- she never does -- but she spent the day on the lot in his massive trailer, an insider said.

Moore was accompanied by her daughter Rumer, 22. She kept a low profile while Kutcher was seen joking around with the audience after the shoot. When Kutcher returned to his trailer, he put his arm around Demi and they acted like a couple, the insider added, They were talking and smiling at each other. Everything seemed just like normal.

Despite their seemingly cheery reunion, a source recently told Us magazine that Moore was humiliated after learning that her Iowa-born husband had an affair with Leal in a San Diego hotel room on September 24, the eve of their sixth wedding anniversary.

She loves him, but can't forgive him for the embarrassment he has caused, the confidante explained.

In between all these rumors, it has been confirmed that Moore's ex-husband, actor Bruce Willis, and his second wife Emma Heming Willis are set to become parents of a baby girl, sometime early next year. Willis, 56, the star of the Die Hard series of films, and Emma, 35, a designer and model, are overjoyed with this news and they look forward to welcoming this newest addition into their family, the rep announced, according to Us magazine.

Willis and Moore separated in 1998 and divorced in 2000, after 13 years of marriage.
