Sharon Osbourne Embarrasses Nick Lachey With Video of Them Making Out (VIDEO)

Nick Lachey probably thought it well behind him, but Sharon Osbourne proved she had a long memory on 'The Talk' (Weekdays, Syndicated on CBS), and wasn't afraid to use it. And thanks to the beauty of television, there's no running or hiding from your past.

Osbourne set him up by talking about how great he looked, and how happy she was that he was "over that old slut you used to be with." She went on like this for awhile, and of course Lachey and everyone in the audience thought she was talking about Lachey's former wife Jessica Simpson.

"Let's go back in time," Osbourne said, setting up a video. "Let's go back and have a look at that old slut!" But it wasn't Simpson at all.

Back in 2003, Lachey had been a guest on 'The Osbourne Family Christmas Special,' and in it he'd participated in a sketch that saw him pushed down onto a bed and straddled by Mrs. Sharon Osbourne herself.

While reliving the moment via Osbourne's clip, 'The Talk' audience howled in shock and laughter as the pair's sexy banter culminated in a passionate kiss, while Lachey hung his head in embarrassment.

"It was in the bed and we're there having this moment," Lachey recalled. "And all I hear in the background is Kelly [Osbourne] in the door saying, 'Mom, you whore!' I'm like, oh my god, I can't even concentrate! There's too much going on!"
