Z100's Jingle Ball 2013 Presented by Aeropostale - Backstage

Selena Gomez really knows how to get her fans’ hearts racing! In her most recent sexy Instagram, Gomez pulls one hell of a sex pot pose in a sheer, lingerie number. Situated in front of mirror in what appears to be a dressing room in Ron Burgundy‘s house, Gomez has her back to the camera in that “I just can’t stop running my hands through my hair” pin up pose that’s been giving boners since the storied days of yore. She looks freaking fantastic.

I’m not really sure how to describe her outfit–calling it a dress seems charitable, so I might just go ahead and say this is full on lingerie. Exceptionally strappy, complicated lingerie. How did she even get into that thing? Who arranged all of those straps?

She looks confident and poised, which is remarkably impressive considering she’s sticking her ass out and making a sexy face while someone snaps a photo. I never understand how models and actors manage to look so hot in photo shoots, because I imagine them as socially horrifying minefields of awkwardness. But she looks beautiful, comfortable, and relaxed, so clearly she has something figured out that is still a big mystery to me.

In a bid to keep fans guessing, Gomez captioned this picture “.. Secret project.” WHAT’S THE SECRET, SELENA? Is there more to it than just looking banging and being confident? Does the have to do with all of those straps? Maybe it’s a musical instructional video about how to get in and out of complicated lingerie. Time will tell.
