Fresh off winning three top awards at last weekend's MTV Video Music Awards, Britney Spears has confirmed she will release a new album before year's end. "Circus" is due Dec. 2 via Jive; the first single is "Womanizer," produced by the Outsyders.

Among the other contributors are Dr. Luke, who wrote and produced the title cut, Danja, Guy Sigsworth, Max Martin and Bloodshy & Avant. The album's release coincides with Spears' 27th birthday.

Last month, Spears told OK Magazine of the new album, "I think it is more urban," adding that she'd been writing everyday on a piano in her living room.

"Circus" is the follow-up to last year's "Blackout," which has sold 894,000 copies in the United States, according to Nielsen SoundScan. The project was largely overshadowed by Spears' tabloid-fodder personal life and her disastrous performance of the single "Gimme More" during the 2007 MTV Video Music Awards in Las Vegas.
