Sharon Osbourne leaving 'America's Got Talent'?

Sharon Osbourne is ostensibly leaving "America's Got Talent," according to a somewhat ambiguous tweet she made. (Of course a tweet.)

Posted around 2 p.m. Tuesday, it reads: "My darling @HowardStern, money is not the reason I'm not returning to @nbcagt, it's because ... "

Yes, the ellipses are hers as if ... Sorry, what was I writing?

According to The Associated Press, NBC has not been informed by Osbourne about her departure plans. Guess they'll have to keep an eye on her feed.

In its seventh season, "America's Got Talent" includes celebrity judges Osbourne, Howie Mandel and Howard Stern and host Nick Canon.
