Superfan, Nicole Richie, got more than she bargained for after she was pulled onstage at Britney's Las Vegas concert.
Despite being chained in dominatrix gear, the star seemed more than happy (excited even?) to play along.
Wonder what it's like to be walked by Britney Spears?
No mind you, afterwards she danced the night away and shared a lovely embrace with Britney Jean herself. She even got a free t-shirt!
