We're not even kidding.
The 33-year-old model, who has starred in campaigns for Calvin Klein, Louis Vuitton, Chanel and Gucci in the past, has revealed she has been sticking to a healthy eating regime dictated by her blood type for over a decade but insists she still gets to consume all her favorite food.
Natalia told HELLO! Fashion, "I've eaten the 'blood type' diet for almost 10 years. It's just about eating what's good for you. I can eat meat, dairy and wheat."
The brunette beauty, who has three children, Lucas Alexander, 13, Neva, eight and Viktor, seven, with her ex-husband Justin Portman and 10-month-old Maxim with her current spouse, Antoine Arnault, began modelling aged 15 and moved to Paris aged 17, but insists her career feels no different than when she first started out.
She recently said, "I don't feel any different than I did the first time I arrived in Paris. I still work on the same principle, that in my life—in everything I do—there is nothing to lose."
The Russian-born model, who grew up selling fruit on a stall in her small neighbourhood, added her difficult upbringing gave her "important tools" to help her become successful.
She explained, "My childhood gave me some very important tools. I'm a fighter you see. I am sure that I wouldn't be able to handle so much, stay so positive, or have this fearlessness, if I haven't lived the life I have."
