"Womanizer," the first single from Britney Spears' upcoming album "Circus," hit U.S. radio outlets this morning. The track, produced by up-and-coming Atlanta team the Outsyders, has a thick, synthy sound that should lend itself to remixes and club play.

Lyrically, "Womanizer" finds Spears rebuffing the advances of man with the "swagger of champions." "Must mistake me as a sucker / To think that I would be a victim not another / Say it, play it how you wanna / But no way I'm ever gonna fall for you," she sings.

Among the other contributors on "Circus" are Dr. Luke, who wrote and produced the title cut, Danja, Guy Sigsworth, Max Martin and Bloodshy & Avant. The album's release on Dec. 2 coincides with Spears' 27th birthday.

Although its video isn't quite ready yet, "Womanizer" will play during Monday's (Sept. 29) episode of the MTV show "The Hills."
