Inside the 'Girls Trip' Premiere

The "Girls Trip" star throws shade at "Real Housewives of Atlanta" star NeNe Leakes and reveals a secret about Taylor Swift.

Tiffany Haddish kept it all the way real when she stopped by "Watch What Happens Live" Sunday night.

Even though the "Girls Trip" star was sitting next to "Real Housewives of Atlanta" star Cynthia Bailey, Tiffany had no problem telling host Andy Cohen how she felt about Cynthia's Bravo co-star, NeNe Leakes.

When Andy asked how Cynthia felt about NeNe throwing shade at her friendship with Kenya Moore, Cynthia brushed it off and said she doesn't "pay NeNe much attention at this point."

"Is she crazy for real?" Tiffany interrupted. "Because you know I did a comedy show with her, and that was a mess."

When Andy asked if NeNe was funny, Tiffany replied, "She was funny at first, but then she got drunk, and then I got concerned."

On Her Dinner With Taylor Swift

A caller asked Tiffany, "You were invited to Taylor Swift's house for dinner. What's one thing that people would be surprised to know about her?"

"She has those old-school, 1980 Polaroid cameras all over, and she takes lots of pictures and makes really beautiful collages," Tiffany said.

The two recently met on the set of "Saturday Night Live." They instantly hit it off, and Taylor invited Tiffany to her house for a potluck dinner, which the latter described in detail when she appeared on "The Ellen DeGeneres Show" earlier this month.

"When she came in, she came immediately into my room and was like, 'I love your comedy. I've been watching you. I know all of your stuff,'" Tiffany said. "She started quoting jokes from like 10 years ago, and I was like, 'Oh, I like this bitch.'"

On Doing Another Groupon With Will and Jada Pinkett Smith

When a caller asked Tiffany if she'd ever do another Groupon with "Girls Trip" co-star Jada Pinkett Smith and her husband, Will Smith, Tiffany was very sure they would.

"Let me tell you something, OK? They will do another Groupon with me," she said. "I know Jada will. I'm not sure if Will will 'cause he be busy, but me and Jada been talking. I was like, 'We should go get some facials, girl. We can go do an exercise class. Also, I found where we can get X-Rays of our bodies for no reason. Just 'cause! We can also do DNA testing -- it's all these great things on there, and she said she would do anything again with me, so we're gonna do it."

Back in July, Tiffany appeared on "Jimmy Kimmel Live" and told the hysterical story about the time she invited the Smiths on a New Orleans swap tour via Groupon.

On Her 'Saturday Night Live' Performance

When Andy asked Tiffany if she was nervous before taking the "SNL" stage as the first African-American female stand-up comic to host the NBC show, Tiffany said no.

"Nervous? Not. Excited? Yes. Very excited, and I just wanted to show and share everything that I have. It was restricted, but still. I showed a lot," she said smiling.

On Landing 'Girls Trip' and Her Stand-Up Career

Tiffany said she'd been doing stand-up since she was 15 years old.

"And I am 21 right now...for the 17th year," she joked.

She said a lot of her cast mates from the 2016 action comedy, "Keanu," were cast in "Girls Trip," and when they read the script, they immediately sent it to Tiffany.

"I read the script, and I was like, 'Somebody been partying with me! They know me!'" she said. "And so I told my agent to get me the job, and then my agent was like, 'Uh, they said that they only wanna see people with names.' And I was like, 'You tell them that I've had a name since 1979. I was born with a name.'"

Tiffany said she ended up auditioning, and when she saw the grapefruit scene, she knew she "got the job -- easy."

"I didn't know it was gonna be this big," she said of the movie. "But I just knew that I would definitely develop relationships with people that I would wanna work with forever."

On Writing Her Memoir

Tiffany brings the funny in her new memoir, "The Last Black Unicorn," but she also discusses some very difficult situations she had to endure while living as a child in foster care.

"It was super hard. It was super hard," Tiffany told Andy about publicly sharing some of her childhood hardships. "But I was challenged, and if you ever challenge me, I'm gonna take you up on it."

On Her Dating No-Nos

During a game of D'Wheel Breakers, Andy spun a wheel of relationship attributes and asked both Tiffany and Cynthia if they'd date a man with the quality he selected. Here are some of Tiffany's best answers:

Would you date a guy with a small penis?

Tiffany: Yes.

Would you date a guy who doesn't have a license?

Tiffany: A driver's license or like a gun license?

Would you date a guy who passes gas in front of you?

Tiffany: Yeah, I would...'cause I'm gonna do it, too. I'm gonna be like, 'Contest!'

Would you date a guy who spent time in jail?

Tiffany: How much time? Like a week or like 17 years?

Would you date a wannabe DJ?

Tiffany: Yeah, I did that already.
