So much for not burning bridges!

A week after filming her final episode of America's Got Talent, Sharon Osbourne says she won't return to NBC in any capacity, even though five years of options remain on her contract.

"They don't want me, and I don't want them," Osbourne tells The Hollywood Reporter. "I never want to hear from them again."

The feud between Osbourne and NBC started this summer, when she announced that she would not return to America's Got Talent, and then claimed that she was leaving because her son, Jack, got fired from the reality show Stars Earn Stripes after he disclosed that he had multiple sclerosis. (NBC said Jack was never officially attached to the show.)

Osbourne goes on to describe network's chairman Bob Greenblatt as "not well" and claims that Greenblatt was miffed about her recent appearance on The Late Show with David Letterman, during which she compared the network to the Titanic.

Osbourne doesn't regret her stint on AGT, however, and says she speaks to her Talent colleagues Howard Stern, Howie Mandel and Nick Cannon regularly and considers them friends.

"Greatest show," she tells THR. "I love the show, but I really don't like NBC, and that's why I wouldn't go back. ... They treat their talent like sh--!"
