And that's showbiz.
On Thursday, the same day the news broke that his wife of six years, Demi Moore
, was filing for divorce
, Ashton Kutcher
proved the show must go – in this case, on the set of Two and a Half Men
The dressed-down comedian, 33, was back to business for his debut season on the CBS comedy at the Warner Bros. studio lot in Burbank to play Walden
, a recently divorced bachelor, who was written into the show when Charlie Sheen
was fired from the hit series
earlier this year.
"I will forever cherish the time I spent with Demi," Kutcher previously said
of the couple's split. "Marriage is one of the most difficult things in the world and unfortunately sometimes they fail."
