Sonja Morgan says she once dated Jack Nicholson.
"He's so much fun," Morgan told host Andy Cohen. "Who hasn't? Don't forget how old I am, and don't forget those days before cellphones, with the old answering machines."
"Nobody nails down Nicholson!" she added before characterizing their relationship as "one big sloppy mess" that occurred "whenever we could."
Nicholson was married to Sandra Knight from 1962 to 1968 and has since dated a number of women, including Anjelica Huston, Rebecca Broussard and Lara Flynn Boyle.
He told The Sun in 2013 that he still hopes to find love.
"I have had everything a man could ask for but no one could say I'm successful with affairs of the heart," he said.
"I would love that one last romance, a real romance, but I'm not very realistic about it happening. What I can't deny is my yearning," he said.
Morgan, who was married to John Morgan from 1998 to 2006, was last linked to Rocco Ancarola.
She has starred on seven seasons of "The Real Housewives of New York City," which premiered a ninth season on Bravo this month.
