The 20-year-old model has been trying to get into shape for her forthcoming appearance at the Victoria's Secret Fashion Show, but she has admitted she never meant to lose as much weight as she did and she's devastated she's lost her womanly curves.

Speaking to People.com, she said: "I really didn't mean to [lose weight]. Like I want boobs. I want my a** back. It's not my fault (she's lost so much weight), my weight fluctuates and so does everybody's and I think that if people are gonna judge, that's the worst you can possibly do because everybody is different."

The brunette beauty - who is the sister of Gigi Hadid - thinks her shrinking frame is down to sticking to a strict diet as well as intense workouts with Rob Piela at Gotham Gym.

She explained: "I've been eating hard protein every day, and working out for three hours every day. It's crazy but I think that if you set your mind to something, I think you can succeed."

And Bella makes sure she sticks to her healthy eating plan and drinks plenty of water when she's travelling around the globe.

She said: "I like to eat healthy and not eat crazy plane food. I like to still make sure my diet is good and I stay hydrated and stuff. That's basically all I do."

Although she's got a body most girls are envious of, Bella has got her own body hangups - just like everyone else.

She explained: "It's crazy because I think that when other people look at all of the Victoria's Secret models or all of the girls [who] are walking, they're like, 'They're not human. They don't have any insecurities.' But I think every single girl [who's] going to be walking probably has an insecurity."
