"Remember, [I was] 25, I had met my husband, but we weren't together. We were just friends," Osbourne began. "So, I'm here, I didn't have a boyfriend — I never did date a lot at that time anyway because I was not very date-able."
But Osbourne got lucky when her friend invited the Brit to a Los Angeles club where she worked that was "full of men." There, Osbourne saw a "very nice, very funny" guy to whom she took a fancy. Luckily, her friend had his phone number and they proceeded to prank call him.
"Anyway, one thing led to another. He actually came to my house and met me and we had a little fling," Osbourne said. "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.
"And that man that I had a fling-y-wing-y with... was Jay Leno," Osbourne revealed, while the audience and her co-hosts erupted in shock (Aisha Tyler's face is especially priceless).
"Whoa, whoa, whoa, I don't know if Sharon is getting the standing ovation or if Jay Leno is getting the standing ovation," Julie Chen joked.
