The 21-year-old supermodel - who signed to IMG Models in 2011 - has admitted no one can replace the 50-year-old catwalk icon, Claudia Schiffer and Naomi Campbell who were the catwalk idols during the '80s and '90s, although she thinks her success in the fashion industry is because the industry needed another iconic generation.

Speaking in a podcast for American Vogue, the blonde beauty said: "Obviously, Cindy [Crawford] and Claudia [Schiffer] and Naomi [Campbell] -- no one can do it better than them in the time that they were in.

"I think that the reason why Kendall [Jenner] and Cara [Delevingne] and Karlie [Kloss] and I are kind of ... able to have this moment right now is because the industry needed a change to be able to welcome in another generation."

Although Gigi and Kendall were previously slammed by Stephanie Seymour - who claimed the new generation of supermodels are not "true models" - the face of Tommy Hilfiger credits social media for her successful career and because it has given her the freedom to explore other paths and it has put her on a platform, which allows people to get to know her on "different levels".

She explained: "We are given the opportunity to spread our wings in so many different industries because people get to know us; they start to understand different levels of our personalities and our talents.

"[Instagram] It's a way that people get to know us other than a face on a page."

However the star - who is currently dating former One Direction band member Zayn Malik - has admitted the numerous outlets put "pressure" on her, which affects her.

Speaking previously about the backlash, she said: "Everyone is affected by the pressures that come from being on social media, and we're all human.

"I'll never say that it doesn't affect me."

But Gigi - who has graced the runway for designer fashion houses Balmain, Versace and Chanel - has "never" hated her appearance.

She said: "I never didn't like my body.

"I was very athletic. I was proud of why my body was the way it was. You do everything you can to be healthy and do what makes you feel good and feel happy."
