Demi Moore, Ashton Kutcher 'act like couple on Two and a Half Men set'

Demi Moore has visited Ashton Kutcher on his CBS show Two and a Half Men.

The couple have been facing rumours of marriage trouble after it was alleged that they spent their sixth anniversary apart.

However, US Weekly reports that Moore was joined by daughter Rumer Willis during her visit to the set of Two and a Half Men.

An insider claimed that Moore wasn't around the actual filming of the sitcom, but spent her day inside Kutcher's trailer.

According to the reports, the pair "acted like a couple" after Kutcher returned to his trailer.

"They were talking and smiling at each other," the insider said. "Everything seemed just like normal."

Although Moore and Kutcher have dismissed rumours that they have split, Kutcher's alleged mistress Sara Leal has come forward saying that she was seduced by the actor after he told her that he and Moore had split.

Kutcher replaced Charlie Sheen in Two and a Half Men, while Moore can be seen in Margin Call.
