Filmed at an L.A. nightclub and directed by Joseph Khan, the man behind Stronger (2000) and Toxic (2004), Britney Spears’s Womanizer video features the singer completely nude in a sauna, covering up her sweaty rackage with her arms. "It's basically saying, 'We know what you're up to,'” explains Spears, “It's about guys cheating on girls . . . It's a girl anthem. That's why I like it.” But everyone else likes it because of Britney’s bare body.
