Ashton Kutcher is baffled by reports his wife Demi Moore is set to take his last name to mark their fourth wedding anniversary.
The funnyman wed Ghost star Moore in September 2005, but the actress has kept her maiden name for all her professional engagements.
Recent tabloid reports claimed Bruce Willis' ex-wife was finally ready to ditch her surname and officially become Mrs. Kutcher - but the actor has no knowledge of the supposed change.
Kutcher admits he's not overly concerned whether or not Moore does legally change her name.
He tells Usmagazine.com, "I think it would be fantastic, but at the same time, it's a name, you know? Like, call me Mr. Moore, I don't care. I've been called a lot worse!"
After a quiet 2009 Kutcher looks set to return to the big screen later this year with his new movie Spread, it will be his first movie since What Happens In Vegas.
He will also appear alongside Kathy Bates and Michelle Pfeiffer in Personal Effects.
