Pictures: Judges And Semi Finalists Attend X Factor USA Viewing Party

In the aftermath of the US X Factor quarter-finals, the star judges and final four were looking their best as finalists and past alumni gathered with them to celebrate the move towards the climax of the show's second season in the US. Big changes were made this year to the judging panel, with Britney Spears and Demi Lovato entering the fray, and though Spears has received some negative criticism, she's in truth managed to hold her own on her first run of the show. Certainly the pair, alongside original judges La Reid and show creator Simon Cowell, looked content to be at the event at Mixology in Los Angeles last night (December 6).

Mixology played host to the viewing party, with semi finalists Tate Stevens, Fifth Harmony, Emblem3 and Carly Rose Sonenclar being revealed. Stevens was looking typically country, wearing a plaid shirt whilst Fifth Harmony looked as delighted as a group who'd avoided elimination in the final showdown would do; they defeated Diamond White to survive another day.
