They did more than kiss.

Gwyneth Paltrow and Timothée Chalamet go all the way in their upcoming film “Marty Supreme,” the actress revealed in her Vanity Fair cover story published Tuesday.

“I mean, we have a lot of sex in this movie,” Paltrow, 52, shared. “There’s a lot — a lot.”

When the interviewer asked Paltrow, “So…you’re in a lot of vulnerable positions with him?,” she replied, “Beyond.”

“Marty Supreme,” directed by Josh Safdie (“Uncut Gems”), is a fictional story inspired by the real professional ping-pong player Marty Reisman, who won several medals at the World Table Tennis Championships between the late 1940s and the 1960s. 

Chalamet, 29, plays main character Marty Mauser. Paltrow plays his love interest, a table tennis WAG.

“He’s such a thinking man’s sex symbol,” Paltrow said about the “A Complete Unknown” actor, who is dating Kylie Jenner.

“He’s just a very polite, properly raised, I was going to say kid,” Paltrow continued. “He’s a man who takes his work really seriously and is a fun partner.”

Paltrow added of her “Marty Supreme” character, “This woman who is married to someone who is in the ping-pong mafia, as it were. They meet and she’s had a pretty tough life, and I think he breathes life back into her, but it’s kind of transactional for them both.”

The co-stars were spotted kissing on the set of the film in New York back in October 2024.

Paltrow later revealed how her husband, Brad Falchuk, felt about her smooching Chalamet.

“Unthreatened, not because T.Chal isn’t AWESOME, but he knows he’s got my whole [heart],” she said in a Q&A on her Instagram Stories.

The following month, Paltrow said on “The Tonight Show Starring Jimmy Fallon” that all of my mom group texts were fire” after the kissing photos went viral.

In her Vanity Fair interview, Paltrow said that having an intimacy coordinator on the set of “Marty Supreme” was a big change for her.

“There’s now something called an intimacy coordinator, which I did not know existed,” she said. “I was like, ‘Girl, I’m from the era where you get naked, you get in bed, the camera’s on.’”

The Oscar winner revealed that she ultimately refused the intimacy coordinator.

“We said, ‘I think we’re good. You can step a little bit back,’ ” she recalled. “I don’t know how it is for kids who are starting out, but… if someone is like, ‘OK, and then he’s going to put his hand here,’ I would feel, as an artist, very stifled by that.”

The steamy role is Paltrow’s first return to the big screen in six years, as her last movie was 2019’s “Avengers: Endgame,” where she reprised her role as Pepper Potts, Iron Man’s (Robert Downey Jr.) love interest. 

Tyler, the Creator will also be in “Marty Supreme,” and Fran Drescher will play Chalamet’s mom.

The film comes out in theaters Christmas Day.
