Katy Perry knows what she’s doing as a judge on American Idol. She just doesn’t know how to do it while wearing a mermaid costume!!

The 37-year-old pop princess was on stage for Sunday night’s live episode of the long-running reality TV music competition show, and since it was Disney night, she opted to dress up as Ariel from The Little Mermaid.

Just one problem: Ariel’s flippers totally f**ked up Katy’s vibe in her judge’s seat! Related: Orlando Bloom Says He And Katy Perry Compete To Do WHAT?!?! At one point, while show host Ryan Seacrest was on camera introducing a performance, Katy abruptly slipped out of her chair and landed HARD on the floor!

Seacrest was caught on screen with a shocked face as Perry tumbled to the floor in a heap. The loud thud could be heard off camera, forcing producers to cut immediately to the judge’s table.
