Some girls love Penn Badgley, some go gaga for Chace Crawford, but it seems like Chace's fans outweigh Penn's -- and it's causing issues for the cast. "Penn was supposed to be the show's break-out star and now it is obviously Chace, and Penn doesn't like it," an insider tells the New York Daily News.

Case in point: at last week's Met Costume Institute gala, Chace was swarmed by fans, invited to George Clooney's after-party, and approached by Tom Cruise and Katie Holmes, who gushed to him about how much they love him and the show. Meanwhile, Penn was ignored like poor little J. "Penn didn't get any love," the insider says. Aww, is Penn turning into a real-life Lonely Boy?
