Adam Lambert is a fan of Kelly Clarkson

Still reveling in his own “American Idol” fame, Adam Lambert told press he’s a big fan of the original Idol Kelly Clarkson, and her new album All I Ever Wanted.

Lavishing praise on the “Since You’ve Been Gone” songstress, Lambert gushed, “The album Kelly just came out with is fantastic.  Great writers, great producers. She wrote a bunch of songs on there, and Katy Perry—my girl—wrote songs on there, too. It’s great.”

As for the recent anti-gay protesters at a stop on the “American Idols” tour, Adam played it cool and encouraged the people to do something more productive with their time.

“I don’t think I’m going to change their minds.  I respect their opinion, but they didn’t need to come to a concert and spread negativity…Go use your energy for something productive.”
