Watch Nicole Richie's Britney Spears Dance-Off
In anticipation of the singer's Femme Fatale concert Monday, Nicole Richie challenged her friend Scotty to a dance-off. Mimicking Spears' original "I'm a Slave 4 U" choreography, the 29-year-old designer and mother of two tweeted that the video was "in honor of my queen, Britney Spears. Can't wait to dance tonight!"
