Sooners' Trevor Knight hasn't called Katy Perry, yet

Pop star Katy Perry caused waves on "College GameDay" this past Saturday morning, when she picked Oklahoma to beat TCU based on the looks of Sooners quarterback Trevor Knight.

"Trevor Knight, call me," said Perry, who also brought a poster of Knight in the shape of a heart.

Well, did Knight make the call?

“I have not called Katy Perry yet,” Knight said Monday.

Knight still has a chance to make his move, though. Perry is scheduled to perform in Tulsa, Oklahoma, later Monday night.
