Her claim to Insta fame? Her 'belfies'
SHE joined Instagram in March 2012. And so far, she has amassed 1.3 million followers.
What makes Ms Jen Selter, 20, a front runner in social media? Her bum.
Her Instagram followers include fellow Instagram queen Rihanna and National Basketball Association star Amar'e Stoudemire, the New York Post reported.
Ms Selter, who is 1.7m tall and weighs 50kg, has perfected the art of the "belfie" (bum and selfie).
Apart from her massive fan following on Instagram, she has 505,000 likes on her Facebook page. On Twitter, she has 90,000 followers and counting, The Huffington Post reported.
"I don't really post a lot of face pictures," said Ms Selter, whose handle is @jenselter.
"I mainly do body selfies. Not that I care what people think, but they don't care. They don't want to see my face."
How did her posterior gain a cult following?
After finishing high school, she took some cosmetology classes while holding side gigs at a plastic surgeon's office and at a gym. Then, she started working out and - boom - her butt began ballooning.
She has been accused of going under the knife and has been called many unflattering things. But she is not perturbed: "I've seen fake butts, and they're nicer. They look nothing like mine. I see it as a compliment."
