'I want boobs... I want my a** back': Bella Hadid says she 'didn't mean' to lose so much weight ahead of Victoria's Secret Fashion Show

She's been working hard to prepare for her debut at the Victoria's Secret Fashion Show.

But speaking with People, Bella Hadid admitted that she had lost a bit more weight than she intended from her rigorous workout.

'I really didn’t mean to [lose weight]. Like I want boobs. I want my a** back,' the 20-year-old model shared.

However, the younger sister of star Gigi Hadid clarified that 'it's not my fault,' noting that her weight fluctuates 'so much.'

'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,' she said, shooting down criticism of her body.

Bella explained that she has lost weight from sticking to a strict diet as well as intense workouts with Rob Piela at Gotham Gym, a popular training spot for VS models, including sister Gigi.

'I wish my a** was bigger' The brunette beauty listed her derriere as an insecurity after 'accidentally' losing too much weight on her strict diet and exercise regimen (pictured, R, in a photo shared to Instagram in August)

She calls Rob 'the best,' noting that she only feels comfortable training if it is just the two of them. 'If I am working with other people, I freak out.'

'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,' she said.

And the daughter of The Real Housewives of Beverly Hills alum Yolanda Foster shared that she keeps to her strict diet, even when traveling.

Thrilled: At the end of last month Bella shared an excited video to Instagram announcing that she would be making her debut in the fashion show this year

'I like to eat healthy and not eat crazy plane food,' Bella explained, adding: 'I like to still make sure my diet is good and I stay hydrated and stuff. That’s basically all I do.'

But Bella does support having a cheat day, telling People that she would be eating pasta after wrapping up her VS fitting.

Her enviable figure aside, Bella insisted that she, along with 'every single person in the world' has insecurities.

Getting ready: The model was seen heading to a fitting on October 30 for the upcoming Victoria's Secret Fashion Show, which airs on CBS on December 5

Work a laid-back denim look like Bella in Second Skin Overalls

Once again, Bella Hadid proved she had what it takes to be successful at her new job as a Victoria’s Secret model, when she stepped out in a low cut denim jumpsuit this week. The flared jumpsuit by Second Skin Overalls managed to flatter her figure, while staying modern and fresh.

Choosing a high-waisted design, with a low-cut zip detailing, Hadid managed to avoid any out-of-date 70s vibes and maintain her trend-setter status.

Hadid’s jumpsuit can still be purchased by clicking right, or you can shop other alternatives in our edit below.

This look is great for any occasion as it looks relaxed and laid-back, but with the addition of heels and some jewelry would look great for a night out. The Stella McCartney version is almost identical to Bella's, while Missguided has an on-trend alternative at a fraction of the price, for those on a tighter budget.

'It’s crazy because I think that when other people look at all of the VS 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,' Bella said.

Going back to her 'accidental' weight loss, Bella revealed that her insecurity has to do with her butt, sharing: 'I wish my a** was bigger.'

The comments come after it was revealed that sister Gigi was made to wear a poncho in her first Tommy Hilfiger show in 2015 because the casting director found her 'not quite as tall or thin as the other girls,' as reported by Yahoo Style.

Gigi and Bella with both appear in the upcoming Victoria's Secret Fashion Show, which is set to air on CBS on December 5.
