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.

The Winter Kate designer and reality star, 29, was dressed casually in tiny denim shorts and a white tank while her friends whooped and cheered her on in the background.
