Britney Spears Debuts a New Video While X Factor Contestants Sing No. 1 Hits

Britney Spears hit the stage in a black dress.

The X Factor contestants brought their A-game last night for another evening of live performances in LA. We were on hand for the Pepsi LIVE preshow and sat in the audience while front-runners Carly Rose Sonenclar, Tate Stevens, Emblem 3, and the five other remaining contestants sang No. 1 hits. Carly Rose put her own spin on Adele's chart-topping single "Rolling in the Deep" while Tate stuck to his country roots and performed Keith Urban's "Somebody Like You."

The contestants didn't disappoint, but the highlight of the two-hour show went to Britney Spears and the world premiere of her new video with, "Scream & Shout." Britney lent her vocals to the song's intro and chorus and looked incredibly hot dancing throughout the video in an ab-baring minidress. Britney and her fellow judges, L.A. Reid, Simon Cowell, and Demi Lovato, return to the small screen tonight for the double elimination results show.
