Sharon Osbourne says she doesn't know whether she will return as a judge on Season 8 of the TV competition show "America's Got Talent."

"I mean, I never know what I'm doing tomorrow let alone today," Osbourne told Tuesday.

Osbourne said her July 26 tweet saying she doesn't plan to come back next season was meant to clarify remarks her fellow "AGT" judge Howard Stern made on his radio show about her contract negotiations for the upcoming season.

"I just didn't like the fact that it got out that it was because of money. It's not because of money," Osbourne told

"They've asked Howard back, they haven't asked me back. So, who knows in this business?" she said.

"Six years is a long time to be on any show. I love the show. It is actually personally my favorite show on TV. I love what the show does, I love the people I work with. But I would have to think about me, I have to think about what I want to do. I don't know [if I'd return]."
