She might not be known as a sports expert yet, but Katy Perry made a convincing guest picker on ESPN's "College GameDay" show earlier today (October 4). The "Roar" singer gave her hilarious picks for upcoming college football games alongside seasoned sports broadcasters.

Wearing a fuzzy pink sports jersey and bright red and black hair, Perry wasn't shy about picking her teams based on which ones had the cutest players. When asked whether she'd pick TCU or Oklahoma, she chose Oklahoma, saying, “I’m picking this one based one on... looks. Trevor Knight, do you hear me?”

The singer pulled a few more gags before her screen time was up, including ripping a mascot's head off and throwing corn dogs at the camera.
