Nicole Richie was Britney Spears’ newest “slave” during the pop star’s Piece of Me concert in Las Vegas on Tuesday.
Like the singer has done with other famous pals and even her boyfriend, Spears plucked Richie from the crowd and put her in bondage gear, before leading Richie around the stage by a leash.
Spears 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 ;)— Britney Spears (@britneyspears) February 19, 2014
