Nicole Richie may be married to the singer from Good Charlotte, and often dress like a hippie chick, but she’s obviously got nothing against dance-pop. While getting psyched for Britney Spears‘ gig in LA last night, Nicole showed off her dance moves to I’m A Slave 4 U” in the above clip. “Do You REALLY want to challenge me to a Britney dance-off?” she queries a pal in the opening text. “Okkaaaaaayyyy……” Though she doesn’t quite nail the choreography (who could?), she was obviously happy enough with the outcome to write “who’s next?” at the end of the clip. We’re crossing our fingers it’s the Madden twins who take the challenge.
