Katy Perry Falls Out Of Chair On 'American Idol' In Constricting 'The Little Mermaid' Costume

Turns out flippin' your fins won't get you too far! Katy Perry took a tumble during the live taping of "American Idol" on Sunday night while dressed as Princess Ariel from "The Little Mermaid." The "Teenage Dream" singer, who was dressing the part for the show's Disney night, fell backwards out of her chair and was quickly helped up by Luke Bryan and Lionel Richie. "…Swipe to see what almost accidentally killed (Lionel Richie,)" she wrote on Instagram alongside a clip of the moment.
