Jen Selter has the tightest rump on Instagram (sorry, Kim K) and she shows it off day in an day out. With 3 million plus followers the "Belfie" extraordinaire attracts a lot of attention. That's no surprise elter has a body reminiscent of a Greek Goddess. She really is the cat's meow and she knows it. After all, if you've got it, why not flaunt it?

At just 20 years of age she has a bright future ahead of her, no matter the career she so chooses. Selter just inked a deal with The Legacy Agency, a powerful sports oriented agency with clients such as NFL Hall of Fame Quarterback Troy Aikman and former Mets Ace Johan Santana.

According to MensXP, once Selter crossed the 300 thousand follower mark on Instagram she started fielding offers from Nike and New Balance. The brunette beauty works hard for her enviable derriere, toned arms and legs, and washboard abs. She only had one cosmetic procedure, and no -- it wasn't a boob job. Back when Selter was in high school, she went under the knife for a simple nose job. Even if she still had a hook nose, would prospective dates really care? 

Jen's agent, Andrew Witlieb, believes his client can become as popular as another female fitness icon.

"We believe she can be the next Jillian Michaels," said TLA agent Andrew Witlieb.

I'm almost positive record amounts of viewers would turn in to watch Setler motivate contestants on The Biggest Loser. There's just one issue that Setler needs to address. She doesn't have a formal fitness or personal training background.

"Jillian didn't get to where she is until her mid-30s. Jen's going to grow as a person, as a fitness expert, in these next years. She's here for the long term," Witlieb added.

Being a player and being a coach, so to speak, are two wildly different animals. However, if Setler's devotes the same amount of time she takes posting her pictures as she does to learning how to be a master motivator.
