Nicole Richie has made no secret that's she's a massive fan of Britney Spears so it's no surprise that she lapped up the opportunity to join her idol on stage where she was made to walk around on all fours while tied to a chain at the singer's latest Las Vegas show. Saucy!

In the footage shot by a fan at the concert, Britney can be seen dressed in her dominatrix stage ensemble of a fishnet bodysuit with leather detailing while holding onto a chain which Nicole, 27, finds herself chained to with the help of the singer's dancers.

As Britney, 32, sings 'Freak Show,' Nicole is then made to crawl around the stage at the Planet Hollywood Resort and Casino during the S&M-inspired skit and fortunately, she didn't appear to be too humiliated, hysterically laughing throughout the segment.

The mother-of-two even joined in the dance choreography with the dancers making the most of her time in the spotlight. Nicole made sure to grab hold of her idol before exiting the stage, giving Britney a warm hug and posing with a merchandise t-shirt.

The 'Womaniser' singer appeared to be impressed by Nicole's crawling talents and tweeted after the show: “Can we all give a round of applause to @NicoleRichie for playing along in the show tonight? U looked hot crawling on all fours ;)” later adding: “@NicoleRichie Thanks for dancing tonight! Xoxox.”

Nicole revealed herself to be a Britney fan when she shared a video of herself having a dance contest with a male friend, performing an entire dance choreography to the pop star's 2002 hit 'Slave 4 U' – and she was pretty good!
