Sharon Osbourne, Jay Leno Fling: Duo Had Hot Love Affair When She Was In Her 20s! [VIDEO]

Sharon Osbourne sure knows how to keep a secret! As part of a new season of "The Talk" on Monday, during the "Big Secret" segment, Osbourne, 60, revealed that she had a fling with Jay Leno a long time ago. "It's not like it's a dirty little secret," she said nervously before telling her story. "When I was 25, I just moved to America," she explains. "I didn't know many people."

The media personality was a 25-year-old "not very dateable" Brit who had just arrived in Los Angeles circa 1978. "Remember, at 25, I had met my husband but we weren't together. We were just friends," she said as a disclaimer to her story. "So, I'm here, [and] I didn't have a boyfriend -- I never did date a lot at that time anyway because I was not very dateable."

One day, Osbourne recalled, a friend of hers insisted that she head to the club where she worked because it was "full of men." "I come down to this club and it is full of men performing and this one person I think, 'Oh he's very nice, very funny.' So I said to my friend, 'I like him,' and she goes 'I've got his number.'" Sharon and her friend started prank-calling him and even admitted she kept calling him because he "liked her voice."

"One thing led to another," she continued. "He came to my house and met me and then we had a little fling. The fling was more fling for me and not fling enough for him," she said, calling it a "flingy-wingy." "The fling was more of a fling for me and not fling enough for him because a couple of months later he brought around the real love of his life for me to meet, and she was lovely and they took me to Fatburger and showed me around town," she said.

Osbourne then revealed that the identity of her brief fling was none other than late-night talk show host Jay Leno, who married now-wife Mavis Nicholson in 1980. The audience gave her a standing ovation. When asked if the sex was good, Osbourne said, "It was so long ago!" Osbourne wed Black Sabbath rocker Ozzy, 64, in 1982. Leno has not commented on the revelation so far.
