Ricki Lake lost her virginity on set of 'Cry Baby' -- but not to co-star Johnny Depp

With Ricki Lake, no topic is off-limits.

The longtime TV personality showed that's truer than ever during an appearance on "Watch What Happens Live," during which host Andy Cohen eagerly asked her about a variety of NSFW subjects.

Never one to beat around the bush himself, Cohen asked Lake point-blank: “Did you lose your virginity on ‘Hairspray’ or ‘Cry-Baby’?” (Lake's big break was her starring role in 1988's "Hairspray," and "Cry Baby," starring Johnny Depp, came not long later in 1990.)

"'Cry Baby,'" Lake confirmed, adding, "Not to Johnny Depp. Another actor, a really handsome actor. He was very kind to me, and I was very large. I was very happy to get it over with ’cause I was almost 21."

"You were a big gal, and this guy made you feel..." Cohen continued.

"He was really sweet, yeah," Lake said. "My first time was really a good one."

Also among the revelations explored during Lake's appearance: "I Love Lucy" star Lucille Ball was not super polite when the two encountered each other at the 1989 Oscars.

"She wasn't very nice. 'Salty' is putting it mildly," Lake recalled. "She was just, like, ornery. She didn't do anything directly to me, but she was not happy to be there. She died shortly after that."
