DemiAshtonOnSetCheater.jpgOn Friday, Demi Moore visited husband Ashton Kutcher on the set of Two And A Half Men, Us Weekly reports.

Moore, 48, visited her husband, 33, as he shot scenes for an upcoming episode. Said a source:

    "Demi didn't come on the actual shooting set or anything ... but she spent the day on the lot in his massive trailer ... They were talking and smiling at each other. Everything seemed just like normal."

The source notes that Kutcher at one point put his arm around his wife of six years. Moore was joined by 23-year-old daughter Rumer Willis.

Kutcher and Moore have both stayed silent since news broke that Kutcher allegedly had a one-night stand with 22-year-old Sara Leal on the weekend of he and Moore's wedding anniversary.

Kutcher has not denied the encounter. He and Moore have continued to wear their wedding rings, though Moore has looked increasingly thin in recent weeks, with many insiders saying she's been extremely stressed.
