It's always fun to see Anderson Cooper launch into an uncomfortable giggle fit, isn't it?

The "AC360" host joined BFFs Andy Cohen and Kelly Ripa on Wednesday night's "Watch What Happens Live," where he was put on the hot seat about his sexual past.

Cohen really put his bud on the spot, asking him a fan question wondering if he'd ever "been with a woman."

Cooper looked shocked, as Cohen pressed on, asking if his friend was a "gold star gay," a term for a gay man who has never had sex with a member of the opposite sex.

"I don't know what the definition of that is," Cooper said, playing dumb. Thankfully, Cohen spelled it out for him: "Have you had penetration?"

After admitting he's "gone on a date or two with a woman," Ripa got in on the grilling -- accusing him of avoiding to answer.

In the end, Cooper finally copped to "kissing" a woman, but that's it.

Later in the show, all three of them found themselves in the line of fire, as they played a game called "Truth or Drink?"

The game tasked the trio's assistants with answering questions about their bosses ... or take a shot. Ripa's assistant is pregnant, so anytime she passed on answering a question, Kelly had to drink for her.

A few fun facts were gleaned from the segment. Apparently, Anderson isn't a fan of Britney Spears' music, Andy won't have Jillian Michaels on his show again anytime soon and Kelly pees with the door open.

"How will you know when to wipe me?" she joked about why she does it.
