Paul Rudd’s youthful look due to being ‘unbelievably kind’

The secret to Paul Rudd’s eternally youthful look isn’t a skincare routine — it’s kindness.

Restaurant owner Asma Khan opened up about meeting Rudd and Dan Levy at her London eatery, Darjeeling Express, and revealed her opinion on why the “Ant-Man” star, 52, never seems to age.

“He just looks so happy. I think the reason why he looks so young is because he’s a good man,” Khan told Insider Tuesday. “Both his kids were there both times; he’s a very family man. I think he’s a man at peace, and that shows.”

Khan’s photo with Rudd and Levy, 37, went viral not only for the “Friends” alum’s impossibly youthful looks but also over his unexpected friendship with the “Schitt’s Creek” star.

“I never expected [the photo] to go viral the way it did,” Khan said. “At least I would have tagged my restaurant! I didn’t even do that.”

Khan praised the “Clueless” actor for being “unbelievably humble and human and kind” despite being “a big film star.”

“He is the kind of person that you want to be a good guy. He’s more than that,” she gushed. “He’s compassionate and humble.”

The “Chef’s Table” star also shared that Rudd took the time to pose for photos with the restaurant’s staff and even FaceTimed with an employee who had flown to India to care for her father, who contracted COVID-19.

“I thought that was just the most beautiful thing he did,” Khan shared. “He talked to her in an unhurried way.”
