Gwyneth Paltrow offers Timothée Chalamet skincare advice for ‘Marty Supreme’ movie makeup

Even beauty experts can be fooled.

Gwyneth Paltrow had an awkward on-set moment with Timothée Chalamet after mistaking his “Marty Supreme” makeup for real skin concerns.

The Goop founder, 53, revealed on Tuesday’s episode of “The Run-Through with Vogue” podcast that she didn’t realize the pockmarks on Chalamet’s face were faux while filming the upcoming ping-pong drama.

“In ‘Marty Supreme,’ Timothée has pockmarks, and they made his eyes beady with contacts and glasses,” Paltrow explained. “And it’s all makeup.”

When Chalamet, 29, commented on his appearance during filming, Paltrow jumped at the opportunity to share her wellness wisdom. “I was like, ‘Oh, you know, you can do microneedling for that,’” she recalled, laughing.

The “Dune” actor quickly set her straight. “And he’s like, ‘This is makeup!’ I was like, ‘Oh, s–t.’ I didn’t realize,” the actress admitted. “The makeup was so good that I thought he had little acne scars.”

Paltrow praised the film’s makeup team for their realistic work transforming Chalamet for the role. She also clarified that her co-star has “beautiful skin” in real life, adding, “His skin in real life, you’re like, ‘Oh my gosh.’”

She reflected that she’s “never done anything like that where I’m really transformed in the face,” though viewers of her cringeworthy 2001 rom-com “Shallow Hal” — in which she wore a fat suit and prosthetics to play an obese woman — may beg to differ.

In “Marty Supreme,” Chalamet plays Marty Mauser, a character loosely based on 1950s table tennis champion Marty Reisman.

The A24 film, directed by Josh Safdie, follows the young ping-pong prodigy’s chaotic journey from shoe salesman to global champion in 1950s New York City.

Paltrow stars opposite Chalamet as Kay Stone, a married movie star and love interest. The Oscar winner previously teased Vanity Fair in March that she and Chalamet have “a lot” of sex scenes together in the film, calling the experience “beyond” vulnerable.

The movie hits theaters on Dec. 25.
