The campaign, which is titled 'I only wear MAC', features a whole host of cultural icons, including Tiffany Pollard, Beabadoobee, Martha Stewart, and Julia, 34. The actress and model is seen holding onto the subway train pole with tight pin curls in her pink rinsed hair, looking directly to camera.

MAC has tapped “outspoken cultural icons” Martha Stewart, Julia Fox, Tiffany “New York” Pollard, Beabadoobee and Odell Beckham Jr. for its latest campaign titled “I Only Wear MAC .”

If there's one person you can rely on to take part in an OMG beauty campaign, it's Julia Fox. Which is why we're not entirely surprised she's been photographed to promote MAC Cosmetics' new nude lipsticks—posing entirely "naked" on the New York subway.
