Pop star Britney Spears brought her good friend Nicole Richie on to the stage during her show in Las Vegas on Tuesday night.
Spears usually brings a male audience member out for a saucy segment in her Britney: Piece of Me shows, but on Tuesday night, she picked Lionel Richie's daughter.
While onstage, Richie had a leash tied around her neck and was led around the stage on all fours by Spears.
The Circus hitmaker later thanked Richie for her participation, writing in a post on Twitter.com, "Can we all give a round of applause to Nicole Richie for playing along in the show tonight? U (sic) looked hot crawling on all fours." Copyright WENN.com
