I don’t blame Katy Perry for this crush — I’m sure there’s a lot of ladies that feel the same way!!  Earlier today Katy made an appearance on ESPN’S “College Gameday” & she hit on Oklahoma QB Trevor Knight — she wants him to “call her.”  Well it ends up that we have bad news for the superstar — he already has a girlfriend. #wahhh I wonder how feels about all the attention he’s getting now — and is there any chance that he will call her?!  I mean she is Katy Perry — A LOT of fellas would just love for her to hit on them!  Stay tuned & check out the pics of his current boo in the meantime…
