“It’s always glam to the max, slightly haunting, a little weird, and gorgeous,” says Chappell Roan of her iconic, ever out-of-this-world makeup looks. “I think there’s something so special about looking not just beautiful, but striking in a surreal way, while singing sparkly pop songs. It’s giving David Lynch vibes for me.” And there’s no such thing as going too far. “There’s always something in the back of my mind that is saying, ‘Is this bold enough for someone to make a Halloween costume out of it? Is this special enough for people to remember?”

Since Roan’s meteoric rise, the 27-year-old singer and songwriter has built a distinctive on-stage persona, collaborating with MAC Cosmetics to create some of her most memorable looks—including for the Grammys and Saturday Night Live, even transforming into a living Renaissance painting for the VMAs. Now, she’s taking that partnership to the next level as the brand’s new global ambassador.

It’s a full circle moment for Roan. “MAC has always made space for people like me; since day one, they’ve embraced art, queerness, drag, and self-expression,” she says. “I’ve built a special relationship with the MAC team over the years, and they’ve been amazing and thoughtful collaborators on this new journey. I can’t wait for the time when I can share what we’ve made with people everywhere.”

The star’s first campaign for the brand, shot by Inez & Vinoodh, features Roan in a characteristically bold face—a cloud-white complexion, razor-thin brows, and frosted glitter lashes—created by her makeup artist Andrew Dahling. “Film-noir meets high glamour,” is how Dahling describes the look, created using MAC classics such as Cool Teddy lipstick, Full Coverage Foundation in White, and a slew of Paint Pots.

MAC creative director Nicola Formichetti calls Roan “one of the most exciting and powerful artists of this generation, a true creative force who uses beauty as a form of bold, emotional storytelling.” And while Roan’s vision shapes each transformation, she thrives in collaboration with her trusted artists, including Dahling, Dee Carrion, and Ali Scharf. “With the complexity of the looks I wear on stage now, it’s best led by the makeup artists I work with. They know way more than I do, obviously, and I trust them with everything.”

References fuel the process. “Pinterest is our best friend,” she continues. “We each have a little folder of photos, and we kind of compare pictures that we’ve pulled from runway, fashion shoots, oil paintings, films, drag, et cetera. Sometimes they will make a drawing or do the makeup on themselves, so I can see it in real life. We build the look from there.”

As for her MAC favorites, Roan doesn’t stray far from a tried-and-true base. “I powder like crazy!” she says. “We use glitter glue for eyes and cheeks. Brows are usually blocked as well, but recently, I shaved off my brows, so we breeze through that part. I always use a long-wear (usually liquid) lipstick. Sometimes it’s not even lipstick, it’s an eye or cheek pigment. We line with MAC lip liners!”

And when the weather demands it, her team takes the glam even further. “Sometimes when it’s really hot, we waterproof set my face. It’s layers upon layers of makeup, and my skin is always clogged after tour. But…anything for the look.”

With Roan stepping into her new role at MAC, her transformative glam is only set to soar to new heights. In short: Get ready.
