Get ready for the first ever Bad Girl Brain Games! You thought this competition was all about strength, speed and agility? Well, think again! This week, the girls show off their spelling, geography, and pop culture knowledge -- or, in some cases, the lack thereof. Could this be the undoing of the unstoppable Rocky? Because let's just say it wasn't her IQ that got her this far in the competition. Also...the losers get soaked in cow brains and cow blood, because this wouldn't be an All Star Battle challenge without a nauseating Carrie reference amirite? Watch the Sneak Peek and tune in tonight at 8/7c!
