Fresh off her VMAs victory and rumored reunion with Kevin Federline, Britney Spears continues to pound the comeback trail like it was a naughty windshield in need of a good pummelling-by-umbrella. Her latest salvo is the new single "Womanizer," the first track off her upcoming album Circus. According to Us Weekly, Spears started shooting the video this week in Los Angeles under the guidance of "Toxic" helmer Joseph Kahn, donning a wig (another reunion!) and straddling a businessman in what's being called "erotic" choreography. In the meantime, we have the single right here — have a listen (and a Cheeto). [Us]
