Upset that he kissed John Mayer and not her, Jennifer Lawrence and Andy Cohen lock lips ... and then things get very NSFW -- plus, superfan J.Law talks all things Bravo from Scandoval to RHONJ, RHOC, and Summer House.
"He's more your type, I guess," she joked with a teasing smile.
"I mean he is, but, I mean, I am attracted to you. I'd love to kiss you," Andy countered. "Consensually."
Jennifer then made it very clear that he has her consent before asking if this segment was going to be on the air. In the end, it didn't matter, as they both got awkward and giggly when they decided to just go ahead and do it right here and right now.
Almost immediately, things got even dirtier -- she is promoting a raunchy R-rated comedy, after all -- when she waved her hand a certain direction and asked, "Did it do anything? Did it move?" Suffice to say, be careful where you listen to that NSFW conversation after the kiss ... because it didn't end there!
It did not, however, go as far as Jennifer did for her film, "No Hard Feelings," which features a full-on naked fight scene. She told Andy that director Gene Stupnitsky even "double checked with me; he was like, 'you know it's like full frontal,' and I was like, 'Yeah, yeah, yeah.'"
During a game of "Plead the Fifth," Jennifer set the record straight about rumors she had an affair with Liam Hemsworth while she was with Miley Cyrus, which internet sleuths got from the latter's "Flowers" video.
In it, Miley was strutting her single status in a gold gown that many thought was reminiscent of one Jennifer wore when she and Liam attended "The Hunger Games" premiere in 2012.
In two simple words, Jennifer said, "Not true."
"Total rumor," she said. Then, referring to her admission in 2015 that they'd kissed off-camera, she added, "We all know we only kissed one time and it was years after they broke up so I just assumed that was a coincidence. Liam and I grew up together. Liam's real hot. What would you have done?"
She also admitted of her recent appearance on "Hot Ones" that things didn't go down as smoothly as she maybe played it off ... or at least they didn't stay down. The actress said she had about eight minutes to get back up to her suite before she "passionately threw up."
Andy asked about rumors that she might appear in "The Hunger Games" prequel, too, which she shot down instantly ... while also revealing that she took "a lot" from the set of those films.
Talking about the epic concluding moments of the "Vanderpump Rules" reunion, when Raquel Leviss came back after taping and revealed that she and Tom Sandoval had continued to lie about the timeline of his affair on Ariana Madix with her even during the reunion, Jennifer described it as "sickening and bizarre and weird."
Andy then hilariously pulled out a cardboard cutout of Sandoval, giving Jennifer the chance to give her a piece of her mind as if he were right there. She definitely laid into him, but about his skin?
"You have weirdly feminine, in a bad way, skin and there's no amount of spray tan that could ever change the texture of it!" she snarled at the cutout.
She also offered her takes on Scheana Shay watching from the trailer, due to Raquel's restraining order, and was asked if she still thinks James Kennedy -- the show's apparent "new number one guy" -- should still be fired.
At a different point in the show, Andy had her play MFK with Sandoval, James and Tom Schwartz, to which she said, "Obviously we know who I'm killing. I really don't want to shag James Kennedy and I really don't want to marry Schwartz but I guess that's where I landed."
Pivoting to "RHONJ," we almost think she has even more vitriol for the newest member of this cast. Not only did she dig into Teresa Giudice's new husband Luis Ruelas for his apparent botox, she really went in on him when talking about Dolores Catania.
Andy asked where she stands on Dolores cutting down Frank's assertion that Luis left their son high and dry and Jennifer did not hold back. "I totally get Dolores wanting to protect her son from this psychopath that clearly has, like, an army of P.I.s," she said.
