Rachel Zoe is one skinny stylist.

She looked frighteningly thin as she stepped out in a bikini while vacationing with her husband in St. Barts Thursday.

Despite her wafer thin frame, Zoe, 38, who headlines her own Bravo reality show, has long slammed rumors that she suffers from an eating disorder. She told Harper's Bazaar last year that she doesn't get why so many people give her a hard time.

"We've had Audrey Hepburn, we've had Twiggy, we've had Veruschka, we've had Kate Moss," she said. "I'm trying to figure out why I am to blame for skinniness.

"Truthfully, I've never seen myself as being too thin," she adds. "Sometimes I'll look at photos and be like, 'Oh, that's not a good look.' But generally speaking, I'm not too thin."

She admitted that eating sometimes is not a priority.

When she's working on her own, she said it'll sometimes be 7 p.m. and she's only "had coffee and a grapefruit" all day. "It's not that I don't eat," she said. "I eat."

Asked if she eats lunch, she replied: "Truth? I don't. I'm not a lady who lunches; it's a lull in the day."
