Slave for Britney Spears! Nicole Richie joined the pop singer on stage during her Feb. 18 concert at Las Vegas hot spot 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.
