Sharon Osbourne says America’s Got Talent hasn’t asked her back. Whether or not Sharon Osbourne will return to America’s Got Talent next year is anyone’s guess, the TV star said Tuesday. “They haven’t asked me back,” the judge acknowledged during a Television Critics Association panel, adding, “Who knows?”

Osbourne, who first suggested last week in a tweet that she may be leaving America’s Got Talent, also revealed that newcomer Howard Stern has already been asked to stay on for another season. At Tuesday’s panel, during which she was meant to be just discussing The Talk, Osbourne expressed reservations about returning to “AGT” for another go-round.“I don’t know. Six years is a long time to be on any show,” she told the crowd . Osbourne continued, “I have to think about me and what I want to do. I’m so f**king old — I don’t know.”
