Slave for Britney Spears! Nicole Richie joined the pop singer on stage during her Tuesday, Feb. 18 concert at Las Vegas' Planet Hollywood. The 32-year-old fashion designer, and Spears superfan, was pulled up on stage during a raunchy performance of the singer's "Freak Show."
Richie shared photos on Instagram from the wild night that included her crawling like a dog on stage while Spears walked her on a leash. In one snapshot, Richie gives Spears, 32, a big hug while surrounded by her scantily-clad male backup dancers. She captioned the embrace: "#GOODBYE." In a second picture, Richie is seen laughing while holding up a large T-shirt with Spears' face on it.
"Can we all give a round of applause to @NicoleRichie for playing along in the show tonight?" Spears tweeted early in the morning on Feb. 19. "U looked hot crawling on all fours."
The "I'm a Slave 4 U" singer also tweeted Richie directly: "@NicoleRichie Thanks for dancing tonight! xoxox." Richie replied back: "Am I alive?"
