Producer Sean Garrett Completed 3 Tracks For Britney

Beyonce is already hard at work on her next solo album, pulling 12-hour days, reports producer Sean Garrett, who boasts that "the songs are sick." "She's in a place I've never seen her in before," Garrett told MTV Radio. "She's very vibrant, very happy, and her mindset is incredible. She's in a zone."

Meanwhile, Garrett's already finished up three tracks for Britney Spears' upcoming album. They're "trying to do some real crazy-ass stuff that the world is going to love," he said. Garrett has also worked on a song called "London Bridge" for the upcoming solo album from the Black Eyed Peas' Fergie. "It's going to be stupid," Garrett said. "The beat is amazing. I think everyone will get to know Fergie's personality. It's crazy."
