AJ McCarron's girlfriend is Katherine Webb and though the brunette beauty queen (see her bikini photos above and below) is an Auburn graduate, she has chosen sides for tonight's big game and she is choosing the Crimson Tide.

McCarron is the University of Alabama QB and they face Notre Dame tonight in the BCS Championship game.

The nation's No. 1 (ND) and No. 2 (Alabama) in college football will settle the score tonight and battle for BCS National Championship in Miami.

Expect Katherine to be cheering loudly for her QB boyfriend, she used Twitter to send out a photo of her dressed for the game, wearing an Alabama jersey with the number 10 on the front.

That just happens to be AJ's number.
