The Hollywood star is known for her slender physique, which she often flaunts in flattering outfits when on the red carpet. While she may appear confident in her own skin, Amanda admits she has her fair share of hang ups.

"I'd like to say I have a healthy perspective on my body, but I don't," she sighed to Red Magazine. "I know what too thin is, but I get really upset if I overeat or I feel I've gained some weight. I know a lot of girls are like that, but they don't talk about it.

"It sucks! I wish it wasn't a part of me, but it is. But I make sure I exercise, and I love eating healthily. And then I'm okay with wine and cheese and cake once in a while."

Despite her insecurities, Amanda, 30, is one of the hottest names in both the movie and fashion industry, with numerous campaigns under her belt, such as being the face of Givenchy. She follows in the footsteps of beauties including Liv Tyler and Audrey Hepburn, and the brand's CEO Alain Lorenzo is in awe of her.

"Whenever she's in Paris, we go for dinner and she's so much fun, very happy," he smiled of the blonde actress.

In return, Amanda loves working with the label, especially its creative director Riccardo Tisci: "I'm definitely a part of the family with Riccardo and everyone on the team. I feel like they get me. I feel understood."

She fronts its Very Irresistible Givenchy fragrance campaigns and previously gushed about how much of an "honest" collaboration it is. She also praised Givenchy's artistic outlook and how they've helped her feel a part of the fashion industry.
