It looks like there might be another judging panel shakeup in the reality TV competition world. Sharon Osbourne tweeted on Tuesday that she has plans to exit America's Got Talent.

"My darling @HowardStern, money is not the reason I'm not returning to @nbcagt, it's because...," she vaguely tweeted. If Mrs. O meant that she's leaving the show, there is no word yet on whether she will complete the season that is already in progress and simply not return for the next season. NBC chairman Bob Greenblatt said Tuesday afternoon that he has no idea what she's talking about and called the speculation "much ado about nothing."
