At a concert for the Queen’s Jubilee last night, Grace Jones sang Slave to the Rhythm while hula-hooping for the duration of the song. The 64-year-old, wearing a giant red headpiece and shiny bodice worthy of 90s-era Mugler, kept the hoop spinning for four minutes, occasionally throwing her arms into the air, as most of the royal family looked on. No word if she was chewing gum at the same time.
