Fitness model Jen Selter has taken the internet by storm, becoming well known for sharing lots of photos of her derriere on Twitter and Instagram.

The 20-year-old's social networking pages blew up after she started posting photos of her workouts and yoga sessions online, raking in close to three million followers on Instagram in just over a year.

Selter's popularity online has led to lucrative deals with NY20 water and Game Plan Nutrition.

She even landed herself a feature in Vanity Fair magazine's April 2014 issue; and she recently spoke to Britain's Mail Online, revealing that while her backside is 100% real, she has had some other work done.

'I'm Jewish. Jewish girls have big noses," she explains, revealing that she had hers done in her teens. "Probably 1 out of 3 girls I know [has had] a nose job."

Her aim is to motivate and inspire people to get in shape "around the world" she told Mail Online, saying that "hard work and dedication" will get you into the same shape she's in.
