INDIANAPOLIS, Ind. -- Madonna positioned herself as the queen of a new generation of pop stars at the Super Bowl halftime show -- complete with throne -- but didn't have complete control of Sunday night's show.

Guest singer M.I.A. flipped the middle finger to the audience after uttering a barely disguised expletive during a performance of Madonna's new single.

M.I.A. was one of two guests who contributed vocals to the bubblegum pop song, "Give Me All Your Luvin'," along with Nicki Minaj. Dance rockers LMFAO and singer Cee Lo also joined the halftime show.

Madonna seemed like Roman royalty when muscle-bound men carried her extravagant throne across the football field to the stage for her opening song, "Vogue."
