Irina Shayk

Model Irina Shayk does not believe in diets and allowed herself to eat hamburgers and pizza after the birth of her daughter Lea. "I don't believe in diets. I feel like if you want to eat a hamburger or pizza or Spanish jamon, you should do it. This is the secret; just enjoy your life and knowing the balance between eating and working out always helps," Shayk told etonline.com.
