Judy Greer admires her Two and a Half Men co-star Ashton Kutcher for being "super fun and happy" amidst his marriage crisis.

Demi Moore announced that she was to file for divorce from Ashton after six years of marriage yesterday.

Judy plays Ashton's character's ex-girlfriend on the sitcom.

Judy did not notice tension on the set of the show when Demi came to visit Ashton.

"All I can say is that Demi was around all the time and I like her," Judy told E! Online. "Ashton is super fun and happy and people love him. He's great on set. He's great to everybody. He's kind of a breath of fresh air."

Whatever strife was occurring in Ashton's marriage with Demi was not apparent to Judy. Ashton kept conversation purely professional.

"He doesn't talk about his personal life," Judy said.

According to an insider, Demi may have spent so much time on the Two and a Half Men set due to her lack of confidence in Ashton's word.

"Demi's finally ready to move on after all these years because she's sick of feeling like she can't trust Ashton," an insider revealed to Star magazine. "Especially as his star continues to rise with Two and a Half Men, he's become really vague about where - and with whom - he spends his time."

Demi released a statement to the public about she and Ashton's impending annulment on Thursday.

The couple's relationship has been strained for months due to allegations that Ashton cheated on Demi on their sixth wedding anniversary with 22-year-old Sara Leal in September.

The pair will allocate nearly $290 million worth of marital assets between themselves during divorce proceedings. It is unknown when their marriage will be officially dissolved.
