Yidio Video of the Day: Nicole Richie Challenges a Friend to a Britney Spears Dance Off... and She Wins!

Yidio Video of the Day: Nicole Richie Challenges a Friend to a Britney Spears Dance Off... and She Wins! Nicole Richie dances like no one is looking, even though everyone is!

Yesterday, in anticipation of Britney Spears' Femme Fatale tour, Nicole Richie challenged her friend Scotty to bust out his best moves.

The song of choice? Obviously "Slave 4 U," one of the greatest Brit dance jams ever. While the song is overtly sexual, Richie was more playful and silly in denim cutoffs and a white tank.

After the dance battle was over, the 29-year-old mother of two and fashion designer took to Twitter to share the video. The victorious dancer tweeted, "In honor of my queen, Britney Spears. Can't wait to dance tonight!"

We're sure Richie danced the night away but did she mosh with her ex-BFF Paris Hilton? By the sound of Paris' tweet last night she wasn't hanging with Nic, "Having so much fun at the @BritneySpear’s concert with @NickyHilton @KathyHilton and @Whittles2! We love Brit!."

Paris and Nicole first became reality besties on the set of "The Simple Life" and Paris is honing her whining acting skills again with her latest Oxygen show, "The World According to Paris."

Even if you aren't digging Paris' latest endeavor, we suggest you check out the Nicole Richie vs. Scotty "No Rhythm" dance off below the jump!
