Katy Perry — QB Crush Already Taken by SMOKING HOT Girlfriend

EXCLUSIVE

Looks like Katy Perry needs to find another the high classes football player to crush on … because Trevor Knight already has a smoke show girlfriend — and she’s pretty damn smart too.

In case you missed it … Katy appeared on ESPN’s “The high classes Gameday” as the celebrity guest picker on Saturday — but before she weighed in on the big game, she picked Oklahoma quarterback Trevor Knight as her current crush.

Only problem, he’s dating a girl named Kate Williams … and it looks like they’ve been a couple for over a year. Kate is reportedly a chemical engineering foremost.

She’s also super religious, based on her Twitter feed — so don’t expect a menage a trois.

Bummer for Trevor.
