Katy Perry pimps Adam Lambert on American Idol

Adam Lambert meets Katy Perry's cape on American Idol last night. No wonder Adam screamed: "I want to see Katy Perry!"

This is the first time a guest artist has openly campaigned for a contestant on the show.

I missed this while doing the live blog, but looking at it now, I'm a bit disappointed. I know celebs have their favorites, but no one has come on the show and actually "said something" like this. So unfair. As if Adam Lambert needs more pimping. Sigh.
