Did Sharon Osbourne just question Jay Leno's sexual prowess? It sure seems that way.

Last year it was revealed that the Osbourne family matriarch slept with the talk show host in the '70s. Now she's divulging secrets about the brief fling, telling Howard Stern that it was exactly that: brief!

"Well, it only took a minute, so I'll just say, it took a second, that was it," she said of the intimate encounter nearly four decades ago. "It wasn't long enough."

Sharon married Ozzy Osbourne in 1982, but her short-lived relationship with Jay Leno came years prior to her marriage, after she saw Leno perform at a comedy club.

"He came to my house and met me and then we had a little fling," she told Howard Stern. "The fling was more fling for me and not fling enough for him."

Howard, who is no stranger to asking graphic questions, continued grilling "The Talk" co-host about the encounter, even asking the size of Jay's, er, manhood. Sharon then added insult to injury, saying she didn't know, because "you can't see past his chin anyway."

After she admitted that she didn't use protection, Howard Stern tossed out the idea that maybe Jay fathered one of her three children. Sharon quipped, "It would've just have been a chin in a chair."

Our advice for Sharon: Sometimes it's best to let the past stay in the past.
