Kat Walks

Leggy "American Idol" runner-up Katharine McPhee strutted out of a rehearsal studio in Burbank yesterday in a tight black tank, short shorts and platform heels. Idolicious!

While it's rumored that she was rehearsing with an African children's choir for an "American Idol" appearance with Josh Groban, TMZ contacted a FOX rep who denied that Kat will be on tonight's show. We'll see!

Sadly, America has voted on Kat's new single, and they're "Over It."
