Britney Spears made her triumphant return to the music video scene today with will.i.am in Scream & Shout, her first new single in over a year.
The pop superstar officially premiered the video for the futuristic club mix on The X Factor's live show Wednesday night. Earlier this month, audio of the song was leaked to the displeasure of Ms. Spears.
"Can't say I'm thrilled our song leaked," she tweeted on November 18, "but…I AM super excited that my fans seem to love it as much as @iamwill and I do."
After the video premiered, will.i.am thanked his fans for their overwhelmingly positive feedback.
"Wow!!! I feel so excited and full of energy right now!!! I want to #screamANDshout," he tweeted. "Thank you all."
Scream & Shout is from the Black Eyed Peas frontman's upcoming solo venture, willpower.
