Katy Perry has admitted that she plans to follow Simon Cowell’s lead as a guest judge on American Idol. She will be taking pity on no one.

Angry Ape reports that Perry wrote on her Twitter page: “Ok, I must confess, I’m SO excited to guest host on American Idol. I think Simon & I are gonna get along famously. He tells it like it is… & truthfully, that’s how ppl need to hear it.

“This isn’t like ur local high school talent contest. This is AI! Ppl that wanna b in music biz need to know this sh** isn’t a cake walk! (sic).”

She added: “No more pity passing kids on to the next level just cause they have some kinda sob story or cuz they look like a replica of past Idol winners (is it me or does every year have like the nerd, the rocker chick, gospel chick, etc.)

“Anyway, I’m just excited to tell it like it is & high 5 Simon all day. He may be devil of judges but he’s riggght.”
