Jennifer Lawrence Ranks Kardashians, Talks Brad Pitt Rumors and Gets One Epic Surprise on 'WWHL'

With her "Red Sparrow" promo tour coming to an end, the actress joined the Bravo host as the solo guest of the night, where she played a very telling round of "Plead the Fifth," got the "Real Housewives" surprise of a lifetime and addressed some gossip about her personal life.

Here are the 4 moments everyone's talking about:

During a game of Plead the Fifth, Cohen asked J-Law to do something she asked Kim Kardashian to do while she was a guest host for Jimmy Kimmel: rank the Kardashians from favorite to least favorite.

"Kendall, Khloe, Kim, Kourtney ... or Kourtney/Kim ... does Kanye count?" a flustered Lawrence replied. "Kris is at the top. The rest I guess, they're at the bottom." Then, quoting "Sophie's Choice," she added, "Just take my daughter!"

"I ranked them not necessarily correct," she said after. "When you meet them, sometimes they rearrange themselves. They're super down to earth, nice people. They're also not putting anything negative out into the world. I don't get all the hate for them."

Lawrence also pled the fifth when asked to reveal some of her shady nicknames for other celebrities, said she had almost all her ex-boyfriends in her phone still and told Cohen to "bring back Brandi Glanville" to "Real Housewives of Beverly Hills."

One caller brought up a pretty juicy rumor about Lawrence, asking whether she and Brad Pitt were dating. The two were linked by tabloids last year.

"No, I've met him once in like 2013, so it was very random," J-Law replied. "But, I also wasn't like, in a huge hurry to debunk it!"

In a recent interview with Oprah Winfrey, Lawrence revealed the three people she'd love to have a dinner party with would be Scott Disick, Luann De Lesseps and Bethenny Frankel. Leave it to Andy Cohen to make "dreams come true."

The host dropped a curtain on set, to reveal the two "RHONY" stars sitting at a dinner table with a cardboard cutout of Disick. Lawrence's reaction to the surprise was just priceless.

Admitting she was "so nervous" to even be sitting at the same table with them, the three women threw back some wine and talked about Bethnny being shady to Dorit Kemsley on "RHOBH," Lu's new cabaret and how J-Law would make a "great Housewife."

"I would diabolical enough, but still find a way to be likable," Lawrence said. Watch the clip, it's just joyous.

As made clear by the video above, Lawrence is a huge Bravo fan. For a separate Q&A session, Cohen asked his guest for her real thoughts on a few of the network's biggest shows and stars.

The actress wasn't impressed by Teddi Mellencamp joining "RHOBH," saying, "as a person I think she's great, she seems very grounded. Not exciting enough for the show, we need someone more diabolical." She added that she "f-cking" loves Dorit.

She also pleaded with "Vanderpump Rules" star Brittany Cartwright to leave Jax Taylor in the dust for cheating on her. "Brittany please, I have been in these kind of relationships before, you are going to be so much better on your own," she said, looking into the camera. "Get out of there. He's f-cking the Reiki master, I promise!"

Of the new season of "RHONY," she also made Cohen a little uncomfortable by saying the she's most looking forward to "that episode where the ship sinks." "I don't know if that's a sore spot," she added. ICYMI: the women just returned from a trip to Cartagena, Colombia, where they were on what's been described as "the Cruise from Hell."

She also dropped the dreaded C-bomb on Lala Kent:
