Is Sharon Osbourne Quitting America's Got Talent?
She fuels speculation with tweet to fellow judge Howard Stern...
Sharon Osbourne appears to have revealed that she is leaving America's Got Talent in a message she sent to Howard Stern on Twitter.
The 59-year-old tweeted her fellow judge to say: "My darling @HowardStern, money is not the reason I'm not returning to @nbcagt, it's because..."
And speculation is now rife as to whether she is planning to ditch the show mid-series or just not return for the next season.
But NBC boss Robert Greenblatt appeared to have been blindsided by the news when he spoke to a meeting of the Television Critics Association.
He told them: "This is coming out of context and sort of spontaneously, and we don't even know what's going on. And it's probably much ado about nothing."
Osbourne's tweet to radio "shock jock" Stern was in response to a message on his own Twitter feed over the weekend which had said that he "isn't sure if he'll do another season and says Sharon Osbourne may not come back unless she gets more money".
Mariah Carey yesterday signed up to appear on rival show American Idol.
