KATY ROARS OVER FALL FROM GRACE

Blames Idol stint for ruining her reputation

- 

Katy Perry was a judge H on American Idol for seven seasons alongside Lionel Richie and Luke Bryan

SPIRALING Katy Perry has gone from a global superstar to a whiny “human piñata” — and insiders claim she’s blaming her American Idol gig for her hitting rock bottom.

“Katy is at the end of her rope! She’s faced a backlash that’s unprecedented for an artist who didn’t do anything criminal,” a pal tells GLOBE. “And she’s convinced it all started with American Idol.”

Sources claim the Teenage Dream songbird, 40, pins her downfall on Idol producers who painted her as the show’s villain.

“Katy thought she was elevating her career as a judge on Idol, but now she says it left her overexposed and made her a punchline,” adds a snitch. “Katy wishes she’d never done the show.”
