A SHOW OF NORMALITY Kelly Clarkson caught a performance of “Finding Neverland” on a recent trip to New York and didn’t call ahead for any special treatment, we hear. “No one knew she was coming,” says a source. “She bought tickets on her own — she didn’t even ask for house seats or comps.” We’re told the singer went backstage after the show and gushed (with wet eyes) to the cast about how much she loved the show. Clarkson also took photos with everyone and was “one of the loveliest” of the celebs who’ve visited.
