Pop diva Beyonce thrilled the Super Bowl crowd with a pyrotechnic half-time spectacular that doubled as a much-anticipated Destiny\'s Child reunion. Fireworks burst into the sky from the Superdome field just vacated by the game-leading Baltimore Ravens and lagging San Franciso 49ers as the 31-year-old chart-topper took the stage with \"Crazy in Love.\" Blowing a kiss to the live television camera after her opening number, she looked relieved to get the much-hyped, 15-minute show under way, but the real treat came when Destiny\'s Child bandmates Kelly Rowland and Michelle Williams joined her on stage. They appeared in matching Rubin Singer black leather warrior-woman bodysuits and dizzying stilettos as did an ever-growing, all-female army of dancers, with musicians cast off on the sidelines. \"Bootylicious,\" \"Halo\" and \"Single Ladies (Put a Ring on It)\" rounded out the greatest-hits performance with a sci-fi edge that set it apart from Madonna\'s hyperactive Super Bowl half-time effort last year. \"Thank you for this moment,\" a beaming Beyonce told the cheering crowd at the conclusion. \"God bless you all.\" Beyonce had promised to sing live at the Super Bowl, acknowledging that she had sung over a pre-recorded version of \"The Star-Spangled Banner\" at President Barack Obama\'s second-term inauguration on January 21. Singing the pre-game national anthem Sunday was Alicia Keys, performing solo at a grand piano, after Jennifer Hudson and the Sandy Hook Elementary School choir from Newtown, Connecticut sang \"America the Beautiful.\" The school was the scene of one of the worst mass murders in US history in December when a lone young gunman cut down 20 pupils and six teachers before taking his own life. He had earlier killed his mother at their home.
