Breaking news: Paul Rudd’s mustache, which he grew out for Anchorman 2, is no longer with us. “Just yesterday I had a mustache, and I had to shave it off, and I’m kinda sad about that,” he told us at last night’s opening of Neil Labute’s Reasons to Be Happy at the Lucille Lortel Theatre. But it looked so great (meaning horrible) in that Lonely Island video! Speaking of which, does Rudd have a secret love of the nightlife? “Do I look like someone who really likes going to clubs?” he asked us. As a matter of fact … no. That explains why he never ages.
