"I want to scream and shout / And let it all out," will.i.am and Britney Spears sing in the hook of 'Scream and Shout.' Something tells us that may be especially true for the former Black Eyed Peas frontman, but for all the wrong reasons. The highly anticipated track leaked to the web!

'Scream and Shout' was slated to debut on Monday, Nov. 19 on KIIS FM in Los Angeles. The song was scheduled to see the light of day promptly at 12 PM PT, according to a tweet from one of the DJs. However, shortly after the news was confirm, the song made its premature debut online.

Spears is particularly excited about the song. When asked about working with Will, she gushed, “He’s fun. You just have to hear it. He’s just, like, a little radical genius scientist in the studio when he’s in there, and he just knows what he’s doing, so just to be able to do a song with him is really fun.”

Will.i.am, while proud of his work, is likely really pressed that it's hitting airwaves early. He pushed back his new album, '#willpower,' when his laptop was stolen and an entire set of songs leaked. The record was originally set to hit shelves Oct. 15, but the hardworking Will scrapped the entire collection (which included a different Spears collabo called 'Sexy Sexy') when the songs first leaked and started from scratch. Here's hoping he doesn't have to go back to the drawing board again.
