Sonja Morgan details 'sloppy' hookups with Jack Nicholson

Ever wonder what a night is like with Jack Nicholson? According to one celebrity, things can get messy.

"Real Housewives of New York" star Sonja Morgan revealed this week that she had an on-and-off relationship with Nicholson years ago, but it wasn't exactly romantic. On "Watch What Happens Live," Andy Cohen asked the 53-year-old if she would ever consider dating Nicholson -- when she revealed she already has!

"Who hasn't?!" she exclaimed, high-fiving Cohen.

"Did you have more than one night with him?" Cohen pressed.

"Nobody nails down Nicholson!" she replied, adding, "One big sloppy mess whenever we could!"

Nicholson was briefly married in the 1960s, but he's technically been a single man for nearly fifty years. He had a long-term relationship with Angelica Huston for more than a decade, but none of his five children are hers.

Morgan, a New York City socialite, was married from 1998 to 2006 and has one daughter, Quincy Adams Morgan.

Cohen also showed an old photo of Morgan with now-president Donald Trump and asked if Morgan had ever dated him.

"No, we're friends," she said. "We were always friends, and I want to his wedding, his ex-wife Ivana's wedding, and friends separately. Friends of the family!"
