Jen Selter: Does this Instagram star have the best bum in the world?

Step aside Kim Kardashian and Jennifer Lopez, there’s a new bum in town.

Jen Selter has become an online phenomenon after Instagram pictures of her perfectly pert posterior went viral and now boasts over 2 million followers on Instagram – that’s 840,000 more than J.Lo, if you’re counting.

The 20-year-old New Yorker and her bum have just joined The Legacy Agency, which represents some of the biggest sports stars in the US, paving the way for extremely lucrative sponsorship deals.

You might not know her yet but she reckons she’s pretty famous in and around the gymnasiums of NYC.

'I'm recognized wherever I am,' said Jen. 'I don't really go to public gyms anymore just because it is a whole big scene when I'm there. I don't like being watched.'

Jen realised she was on to a winner after she began hitting the gym and noticing the changes to her derriere.

She joined Instagram back in March 2012 and began to document her progress, with photos of her perfect bum garnering nearly 150,000 likes.

The selfies mainly feature Jen at her favourite place, the gym, in a variety of bum enhancing poses or posing in and around NYC.

The former gym worker admits that she mainly posts body shots as her followers ‘don’t want to see my face’.

Rarely out of her leggings and trainers, Jen seems to have perfected an arch move that quite frankly makes planking look like a piece of cake.

Thanks to her online success, Jen has since quit her day job having secured sponsorship deals with a water brand, NY20, and a nutrition supplement company, Game Plan Nutrition.

Jen’s one of the first people to grab their 15 minutes of fame through Instagram but no doubt she won’t be the last.
