LOS ANGELES (AP) – Scary Spice will be the new judge on “America’s Got Talent.” Spice Girl Melanie Brown will join Howard Stern and Howie Mandel on the judges’ panel. She replaces Sharon Osbourne, who quit the show in August over a dispute with NBC. Osbourne had claimed NBC fired her son, Jack, from its show “Stars Earn Stripes” after he was diagnosed with multiple sclerosis. NBC denies that. “America’s Got Talent” is accepting submissions for this summer’s season at www.agtauditions.com .
