To kick things off (no pun intended) Christina Aguilera will be treating us to an 8 minute version of the National Anthem. Fergie, Will I Am and the other two no-name Black Eyed Peas are headlining the halftime show. Slash and Usher are rumored to be the surprise guests at halftime. Im sure Kid Rock will find a way to squeeze in an appearance too since it's Dallas and he is sooooo American.
Commentators will probably talk about Bret Favre a lot, but he wont actually be at the game. I'm guessing Wiz Khalifa will be on screen at some point since he is from Pittsburgh and has a hit song out right now called Black and Yellow.
