Hot mom alert! In anticipation of Britney Spears' Femme Fatale concert stop Monday 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."
"In honor of my queen, @BritneySpears - Can't wait to dance tonight!" She Tweeted.
In the video, the mother of two showed some impressively fluid and sexy moves alongside her male friend – who didn't fare as well in the impromptu dance challenge.
