On the Scene: M.I.A., Kelis, Ameriie, JoJo, Bruno Mars, Travie McCoy

M.I.A. invaded Day 3 of the Big Chill Festival at Eastnor Castle Deer Park in Ledbury, England, on Saturday (Aug. 7). The music rebel, wearing goggles and a catsuit printed with her album artwork, invited concertgoers to join her onstage for “Paper Planes,” but had to cut her set short when hundreds rushed the stage during her headline appearance.

Dance diva Kelis, rocking a Cleopatra-inspired look with a gold beaded dress, performed tunes from her Flesh Tone album at the U.K.’s Big Chill Festival.

Ameriie and fiancé Lenny Nicholson spent their Saturday night partying at PURE nightclub at Caesars Palace in Las Vegas where she performed.

JoJo put her best foot forward at Penelope and Coco’s Classic Boot Collection and 2011 Spring Preview at Hold Up Art Gallery in Los Angeles. The 19-year-old singer’s mixtape is scheduled for release this month.

Bruno Mars and his “Billionaire” collaborator Travie McCoy scored some swag backstage at the Teen Choice Awards 2010 gift retreat at the Gibson Amphitheatre in Universal City.
