The revolving door that has been the judges table on America's Got Talent may soon be facing another exit.

Sharon Osbourne tweeted a cryptic message to her follow judge Howard Stern and said that, "money is not the reason I'm returning to @nbcagt, it's because..." The news came as even more of a surprise because according to Daily Mail, Sharon had yet to even notify the show of her plans to exit!

So why might Sharon leave America's Got Talent? Part of the deal for Howard signing on as a judge was that the show had to be moved from NYC and the weekly commute from LA is becoming too much for her. On top of that, she's already filming chat show The Talk on the west coast. Plus, Sharon has personal reasons for wanting to be home more. Not only did her son Jack celebrate the birth of his first child last April, he also recently announced that he is suffering from multiple sclerosis.

NBC President of Alternative and Late Night Programming Paul Teledgy has not commented on the tweet or confirmed Sharon's status, but told reporters she is "a big part of the show."
