Britney Spears and Will.i.am's new music video for "Scream and Shout" was supposed to premiere last Thursday, and though the full-length video will debut on The X Factor on Wednesday, the stars have released a sneak peek at the vid in this promo clip. Hopefully they'll release another one in the next 48 hours!

The track is from Will's forthcoming solo album, #willpower, which also features collaborations with Justin Bieber and Ne-Yo, among others. "I just saw the final video for #screamANDshout," Will tweeted over the weekend. "I'm so happy and excited for everyone to see it...this week is going to be a good week."
