Ashton Kutcher's one-night-stand with 22-year-old Sara Leal may be eating away at Demi Moore, but the two aren't ready to throw in the towel just yet.
On Friday, Moore, 48, visited her husband of six years while he shot scenes for an upcoming episode of Two and a Half Men, Us Weekly can exclusively report.
"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 says.
Joined by her 23-year-old daughter Rumer (with ex-husband Bruce Willis), the Five director kept a low-profile as Kutcher, 33, "joked 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 adds. "They were talking and smiling at each other. Everything seemed just like normal."
Despite their seemingly cheery reunion, a source recently told Us that Moore is "humiliated" after learning that her Iowa-born husband had an affair with Leal in a San Diego hotel room on September 24 -- their sixth wedding anniversary.
"She loves him, but can't forgive him for the embarrassment he has caused," the confidante explained.
