She had just moved to the United States -- and was still "just friends" with now-husband Ozzy Osbourne -- when Sharon Osbourne had a fling with talk show host Jay Leno.
The Talk co-host revealed the secret on Monday's episode as part of it's Secret Segment, saying she had a "flingy wingy" with the late-night king when she first moved to Los Angeles at age 25.
Sharon says the two met at a nightclub, and recalls describing the comedian as, "very nice, very funny," to her friend.
Wooing him with her British accent over a prank phone call, she says one thing led to another, and that Jay "actually came to my house and met me and we had a little fling."
The hookup didn't last, however. Sharon married Black Sabbath frontman Ozzy in 1982, while Jay tied the knot with his now-wife Mavis Nicholson in 1980.
