The 21-year-old stunner was snapped snacking on McDonald's french fries in between takes while shooting a DKNY ad campaign in Times Square on Tuesday.
Dressed in a paisley-print pullover and black-rimmed glasses, the blond beauty held up a fry with a shocked expression on her face, seemingly trying to match the presumed reaction of those who witnessed the pin-thin star devour a little Mickey D's on set.
But fans of the sassy starlet are well aware that Cara's affinity for fast food extends beyond her most recent photoshoot. She posted a pic of herself in September eating McDonald's with fellow model Jourdan Dunn before rocking the catwalk at London Fashion Week.
"My food is faster than yours!!! #fashionweekdietplan @officialjdunn," Delevingne captioned the photo of her and Dunn holding McDonald's bags in their mouths while backstage at the Burberry SS14 fashion show.
Work isn't the only time when the busy gal can't seem to contain her fast food cravings.
She was snapped on a late-night food run to the Golden Arches with BFF Rita Ora in early September after a night out on the town in London.
Heck, girl even follows McDonald's on Twitter to ensure she doesn't miss any special deals.
And she's also shamelessly rocked a full-on hamburger suit, proving she's anything but afraid to chow down.
