Sharon Osbourne claims she is determined to leave America's Got Talent. At the recent TCA panels NBC president Bob Greenblatt denied rumors that she wanted to leave the show's judges panel, citing a contract that locked her in for several more seasons. However, Osbourne told the New York Post that she is willing to break her contract and suffer penalties. She claims that she is upset with NBC because the network reneged on a promise to cast her son Jack Osbourne on the upcoming reality series Stars Earn Stripes after he was diagnosed with multiple sclerosis. More details are available from the New York Post and Deadline.
