Who are these girls?

The situation: Nate watching a college football game. Cate walks in, looks at the TV and sees a shot of the cheerleaders on the sidelines. In a very cute, innocent, excited little voice she says...

"Look! It's Daddy's ballerinas!!"


That's right folks, these girls are Daddy's ballerinas. In-ter-es-ting...

(note - I am in no way pledging allegiance to USC...they simply have a monopoly on all decent football cheerleading pictures on Google images...seriously, I even tried searching specifically for UCSD, Stanford, UofU...USC kept popping up...what the?)
