Nicole Richie is a big fan of Britney Spears. In a tribute to the "Womanizer" hitmaker, the former "Simple Life" star is showing off her "I Am a Slave 4 U" moves in dance-off challenge with a friend. "In honor of my queen @BritneySpears," so she tweeted.
Nicole wears a white low-cut tank top and super short denim cut-offs when doing her dance to the sexy tune. Barefooted, she shakes her hips, bends down and spins her body with a plenty of energy. An impressed Kim Kardashian tweeted in response to her video, "Omg this is amazing!"
While posting the video, the mother of two also hinted that she might attend Britney's concert at the Staples Center on June 20. "Can't wait to dance tonight!" wrote the wife of Good Charlotte's Joel Madden on Monday afternoon.
