Britney Spears and Demi Lovato let off some steam after a grueling few weeks on The X Factor yesterday. Along with their fellow judge L.A. Reid and new hosts Khloé Kardashian and Mario Lopez, who brought along his fiancée, Courtney Mazza, Brit and Demi hung out at a party for the program's finalists at The Bazaar inside the SLS Hotel Beverly Hills. Britney, Demi, L.A., and Simon Cowell are now faced with whittling down the remaining 12 contestants to one winner — we'll see the latest developments in the X Factor drama on tomorrow's episode. Before then, though, the gang celebrated together yesterday with Brit's fiancé, Jason Trawick. Now, Demi's got her attention on today's 2012 election. She tweeted late last night, "My first time voting! Make sure to vote! Every vote counts."
