Jen Selter, from New York City, has become an Internet sensation after she started posting pictures of her workout and bootylicious backside. The 20-year-old fitness enthusiast has become somewhat of a celebrity telling the New York Post that she gets recognized wherever she goes.  

Selter, who only began posting her pictures in May 2012, already has over 1.3 million followers on Instagram.

"I'm recognized wherever I am," she told the Post. "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."

Selter's butt photos have not only given her sudden fame but also endorsement deals. The New York native skipped college but says she makes "a lot more money than a graduate would be making" from deals with NY20, a NYC water company and nutrition supplement company Game Plan Nutrition.

"I see myself motivating and inspiring everyone around the world," she said adding that one day she hopes to create her own line of workout clothes and open a chain "of like cool gyms, like with some glowing stuff."  

Along with her instant success came a lot of criticism. On just about a daily basis Selter said she encounters people who question her rounded butt is real or not. She insists it is saying the only work she's had done was on her nose when she a teenager. Regardless of the negative comment Selter gets she still has millions of fans, both male and female.

"My initial impression was sort of like a fascination," NYC fashion photographer Ben Fink Shapiro told the paper. "It's sort of like a silent, miraculous observation. Like, how is a body shaped like this?"

He also said his girlfriend is "equally as fascinated and obsessed with her."

"I'm very proud of her because this is a girl who didn't go to college, and she was able to build up this social media in such a way that she has become famous and she is an inspiration and motivation for so many people," her mother Jill Weinstein said adding that she doesn't want her daughter to end up in Playboy.

So how do you get a booty like Selter's? The 20-year-old said her fitness regimen includes donkey kicks, doggie hydrant and tons of squats.

"Your butt is your biggest muscle," she said. "There are so many ways to shape it and firm it up."
