Katy Perry's crazy football weekend

Katy Perry tore up Oxford, Miss., on Saturday as she went to her first college football game.

And she had a crazy time.

She appeared on ESPN's College Game Day, where she threw a corn dog at the camera.

She gave a shout-out to Oklahoma Sooners quarterback Trevor Knight to call her.

When asked to pick a winner in the Oklahoma-TCU game, she said, “I’m picking this one based on looks. Trevor Knight, do you hear me? The quarterback for Oklahoma, we don’t mind. So I’m going to go with him. Trevor Knight, call me!”

His brother, Tyler Knight, offered to take her out.

She hugged the mascot - and we mean really hugged.

She proudly tweeted about the big win.

And she chugged a beer and jumped off a bar in true college fashion.
