Joining forces for another collaboration, Britney Spears and Will.i.am have already teamed up for “Big Fat Bass” on Britney’s Femme Fatale album. However, “Scream and Shout” is like nothing we’ve ever heard! Britney Spears embraces an alter-ego while Will.i.am continues to spin his signature electric beats. To quote Britney, “when you hear this in the club, you will turn it up!”
