The 21-year-old supermodel has been announced as the face of the sportswear giant's Perfect Never campaign, which is a bid to encourage women to use physical activity as a way to momentarily "escape" from social pressures.

The catwalk icon - who was previously crowned the captain of Malibu high School's varsity volleyball team in 2013 - has revealed fitness is the "only time" she can be at peace.

Speaking about fitness as part of the campaign, the blonde beauty said: "When I was a competitive athlete, I used to be so focused on being perfect that my coaches would take me out of competing all together. I'd focus on my mistakes which would breed more missteps - a domino effect. Until I learned to change the channel, to re-focus, re-set. It was my mistakes, my imperfections that motivated me most."

And Gigi - who is currently dating 'Pillowtalk' hitmaker Zayn Malik - has revealed she is a strong believer in Reebok's three prominent principles that exercise holds social, physical and mental benefits of fitness.

Gigi said: "Working out isn't only physical for me. It's mental. It helps me escape the noise in my head. It's the only time my mind goes quiet."

And Gigi has admitted she is "honoured" to join forces with the label and is "committed" to pushing boundaries for the female sex in her fashion ventures.

Alongside a picture posted to her Instagram account, which captures the star building up a sweat whilst boxing, she wrote: "'Perfect' never exceeds expectation. It doesn't allow us to reach our full potential. May we be confident and have love for who we are, but, in all that we are passionate about, may we always remember that Good is the enemy of GREAT. Don't settle. I'm so honoured to join a campaign that's committed to pushing these boundaries for women. Thank you @reebokwomenfor creating such an inspiring message of female empowerment - I'm so excited to be a part of it! #PerfectNever#BeMoreHuman #[email protected] #ad (sic)."
