As part of "The Talk's" Big Secret segment yesterday, Sharon Osbourne, 60, revealed a doozy about a fling she had before settling down with rocker husband Ozzy.

"I just don't know why I never discussed it before or shared it or anything," she said.

Saying it wasn't a dirty secret or anything, the former "America's Got Talent" judge admitted that when she first moved to the United States at 25, she had a "flingy wingy" with Jay Leno.

"I didn't know many people," she added. "I had met my husband [Ozzy] but we weren't together, we were just friends."

A friend begged Osbourne to come to this club where there were supposedly a lot of available men.

"I come down to this club and it is full of men performing and this one person I think, said, "Oh he's very nice, very funny." So I said to my friend, 'I like him.'"

In fact, she said she prank-called Leno, which led to a meeting.

"One thing led to another, he actually, he came to my house and met me and then we had a little fling," she said.

But the hookup didn't last.

"A couple months into it, he brought around the real love of his life for me to meet," she said. "She was lovely and they took me to Fatburger and showed me around town."

Osbourne said she and the "Tonight Show" host remained friends over the years.
