Sammi Sweetheart and Deena Cortese Cheer on Stage at Jingle Ball in Philadelphia on December 7, 2011
We can't think of two louder and crazier people to co-host Jingle Ball 2011 in Philadelphia than Jersey Shore's very own Sammi and Deena.
The two guidettes were seen posing for pics backstage, showing off their sparkly outfits, and screaming into the mics to get the audience (fist) pumped for a night of live music.
