Timothée Chalamet’s plus-one game is unmatched.

The actor brought his mom, Nicole Flender, as his date to the New York City premiere of “Marty Supreme” on Tuesday night — and the duo coordinated in head-to-toe neon orange.

Chalamet, 29, wore a double-breasted Tom Ford suit designed by creative director Haider Ackermann, paired with a silk shirt and a fringed scarf in the same tangerine shade.

Stylist Taylor McNeill completed the look with Chrome Hearts glasses, a Cartier Panthère de Cartier diamond pendant necklace and a custom orange Urban Jurgensen watch.

Flender matched her famous son in Cult Gaia’s Phoebe Halter-Neck Gown in persimmon ($1,198), accessorizing with coordinating heels, orange drop earrings and Frances Valentine’s Stardust Sequined Bag ($209).

The mother-son twinning moment echoed a similar outing just last week, when Chalamet and his girlfriend, Kylie Jenner, turned heads in matching custom Chrome Hearts orange leather looks at the film’s Los Angeles premiere.

Orange has become the signature color of the “Marty Supreme” rollout, referencing the orange ping-pong balls that play a role in the Josh Safdie-directed film, in which Chalamet portrays table-tennis champion Marty Mauser.

It’s far from the first time Flender has joined her son on the red carpet. The real estate agent and former Broadway dancer accompanied Chalamet to the 2018 Oscars when he was nominated for Best Actor for “Call Me by Your Name,” and again at this year’s Vanity Fair Oscar Party.

Flender has been vocal about her approval of Chalamet’s relationship with Jenner, telling Curbed in April that the Kylie Cosmetics founder is “lovely” and “very nice to me.”

The NYC premiere also reunited Chalamet with co-star Gwyneth Paltrow, who plays a retired movie star and his character’s love interest in the 1950s-set sports comedy-drama.

Paltrow, 53, recently recalled a hilariously awkward on-set moment: She offered the actor skincare advice after mistaking his character’s prosthetic pockmarks for real acne scars.

“I was like, ‘Oh, you know, you can do microneedling for that,’” the Goop founder said on “The Run-Through with Vogue” podcast. “And he’s like, ‘This is makeup!’ I was like, ‘Oh, s–t.’”

She clarified that Chalamet, in fact, has “beautiful skin,” adding, “His skin in real life, you’re like, ‘Oh my gosh.’”

As for what Paltrow’s own kids thought of her intimate scenes with the much younger Chalamet? Her daughter Apple, 21, and son Moses, 19, had very different reactions.

“My daughter’s so cool and so punk rock that she’s like, ‘Mom, this is awesome!’” Paltrow told The Hollywood Reporter. “And my son was like, ‘Oh my God, I don’t want to see this.’”
