The story behind Kylie Jenner's scar, that sits unedited on the cover of GQ.

Kylie Jenner has never hidden her scar. The beauty entrepreneur’s millions of fans will have seen her proudly display it on social media, talk about during interviews.

And her much-talked about GQ covershoot is no exception.

The 20-year-old mother-of-one and baby of the Kardashian clan posed for the magazine on the lap of her partner, Travis Scott.

Wearing a high-cut swimsuit, Jenner straddled the rapper, placing her scarred left leg front and centre.

So how did Kylie Jenner get her scar?

Jenner explained the injury during a 2011 fan Q&A via Celebuzz, and it turns out it’s actually the result of a humble game of hide-and-seek.

“When I was about five my sister and I were playing hide-and-seek and I hid inside this really tall-enclosed gate,” she said.

“After a while when my sister didn’t find me I had to climb up on this sharp pole sticking out from the gate.

"I slipped and the pole went into my leg.

"I tried pulling away to get the pole out but it just tore through my whole leg.”

While the injury was no doubt traumatic at the time, the result doesn't faze Jenner. She shared several photos of it over the years, including one in 2015 which she captioned, "I love my scar."

In a culture where pores, wrinkles, blemishes and hairs are erased with the click of a mouse, fans are praising the Kylie Cosmetics founder for wearing her scar so proudly.

"I am happy to see a scar so prominently on display (not even minimised with airbrushing)," wrote one twitter user. "It's one scar. No sad story. It's a big step forward for those of us with many #scars who only see perfect skin on others."

"Kudos @KylieJenner for not covering up her [leg] scar," wrote another. "It’s beautiful. Way to show young girl there’s no such thing as flawless."

"@KylieJenner not having her scar edited out of the #GQ cover is EVERYTHING."
