In anticipation of Britney Spears' Femme Fatale show last night in Los Angeles, Nicole Richie Tweeted a video of herself and a male friend engaged in a silly, spontaneous "dance off" to the pop star's hit "Slave 4 U."
Needless to say, Nicole won ... and has some pretty good moves!
"In honor of my queen, @BritneySpears - Can't wait to dance tonight!" wrote the mother of two, who showcased some impressive hip action (and curves).
The celebrity fashion designer and reality star was dressed casually in tiny denim shorts and a white tank while some friends whooped and cheered her on.
Nic left the lap dances to Britney at the actual concert, however.
