Anjelica Huston's comment about Jack Nicholson's manhood will make you blush: Watch

Anjelica Huston is opening up about her nearly two-decade romance with Jack Nicholson -- and the details of their relationship may make you blush.

The actress appeared on "Watch What Happens Live" alongside RuPaul on Monday night, where she played a round of host Andy Cohen's infamous game, "Plead The Fifth."

Because she declined to reveal a famous man who she had turned down in the past, Huston was forced to "describe Jack Nicholson as a lover in three words."

"Um, um, um. Oh, dear. What is that d-thing?" she turned to Ru.

"Dick," he said nonchalantly.

"That's one word. Very big," the "John Wick 3" actress added.

"He's well endowed?" Cohen followed up.

"Well, for the moment," she shot back. "That was really hard. And sort of inaccurate, but we won't go into it."

Huston and Nicholson dated off and on for 17 years starting in 1973, when the actress moved from New York to Los Angeles. During her recent viral interview with New York Magazine, Huston divulged details on Nicholson's alleged cocaine use during their relationship.

"Never took overt amounts. He was never a guzzler," she said. "I think Jack sort of used it, probably like Freud did, in a rather smart way. Jack always had a bit of a problem with physical lethargy. He was tired, and I think probably, at a certain age, a little bump would cheer him up. Like espresso."

Huston further opened up about her relationship with Nicholson in her second memoir, "Watch Me," which came out in 2014. The previous year, she released another memoir about her early life titled, "A Story Lately Told."

Huston would go on to marry artist Robert Graham in 1992. They lived together until his death in 2008.
