Top Model contestant redefines beauty

She was cruelly nicknamed 'zebra' and 'cow' in her earlier years, but Chantelle Brown-Young has proved the haters wrong by nabbing a modelling opportunity millions would kill for.

The teenager has fulfilled a lifelong dream by being chosen as one of 14 contestants on the latest round of America's Next Top Model.

Brown-Young suffers from vitiligo, an incurable condition that causes areas of the skin to have no pigment.

"A lot of people have a story and a background, but mine is painted on my body," she says in her plea video for the reality show.

She may be only 19, but Brown-Young (also known as Winnie Harlow) is already pushing boundaries and challenging societal stereotypes of what it means to be beautiful.

"I have my flaws, but I love them and embrace them, they are mine," she said in a 2011 video called "Vitiligo: A Skin Condition not a Life Changer" (see below).

After developing the rare skin condition as a child, Brown-Young battled through years of bullying, and at her lowest point even pondered suicide.

Today, she has emerged triumphant, stating, "It's just skin, people have black skin, people have brown skin, I have both."

Brown-Young's social media accounts reveal she has already graced the catwalk dozens of times, starred in a music video and last month, was photographed by Nick Knight, who has lensed everyone from Kate Moss to Karlie Kloss.

The young model describes herself as a 'vitiligo spokesmodel' on Instagram where she has more than 100,000 followers, and she was recently invited back to her high school to give a motivational talk about the discrimination she has faced.
