Model Irina Shayk: 'I Don't Understand How People Don't Eat – I Eat Everything!'

There is no denying that Irina Shayk has an amazing body (have you seen those bikini pics?!), but the supermodel insists it doesn’t come from depriving herself.

“I’m a model, but I love to eat,” Shayk – who is dating Bradley Cooper – told PEOPLE at Porcelanosa New York City Showroom Grand Opening. “Sometimes when I’m on set I keep eating and people are like, ‘You really eat that?’ I’m like, ‘Yes, I do.’ ”

And some of her favorite foods include dishes from her childhood.

“When I was growing up in Russia my grandmothers would cook the best pancakes in the world: the best meatballs, the best dumplings,” she says. “So I really, really love food. And I don’t understand how people don’t eat. I do eat everything.”

Then what’s the supermodel’s secret to looking so good?

“Well, I have good genes [so] I thank my family,” Shayk says. “But I work out a lot. I do boxing, I do a little jiu jitsu which I am obsessed with. It is so much fun [and] I have the best trainer. You have to find the best workout for your body. You have to balance between eating and working out.”
