Olivia Munn’s obsession with all things skin care permeates all aspects of her life — she’s always giving advice on Instagram, she is the face of Proactiv and she’s always testing new looks for the red carpet. As it so happens, while she’s totally a self-described skin fanatic, her obsession hasn’t really rubbed off on boyfriend Aaron Rodgers, 31. That’s because he’s already in pretty good shape with his skin thanks to his clean eating habits and workout routine as quarterback for the Green Bay Packers, says Munn.

“Since we’ve gotten together, he eats really healthy and he works out a lot,” the 35-year-old star of X:Men Apocalypse tells PeopleStyle in an interview for our new issue, on newsstands Friday. “It’s crazy because he’ll just do one thing and all of a sudden it just works so well. Like he starts to eat a different way and his whole body changes and he looks healthier and happier and more fit. I’m like how does he do that?!”

It’s a minimalist routine, for sure. “He doesn’t get manicures or pedicures,” she says. “He’s a football player but everything is just kind of perfect on him.”

However, she has influenced him in one way — his use of sunscreen, and encouraging him to wear it more, more and more. “It’s important to me that he wears sunscreen because my biological father had skin cancer,” says Munn. “So that’s really important to me.”

The two have been dating since 2014.
