Latest social media trend is all about the booty

Unless you've been living under a rock far, faraway from social media - you're pretty familiar with selfies. But a new trend that's sweeping the self-obsessed Internet world is bearing a different set of cheeks. It's called a belfie and incase the picture doesn't spell it out for you, it's all about the booty.

Plenty of celebs have jumped on the belfie train- obviously Kim Kardashian, Kim Kardashian and friends, Rihanna- with her more subtle belfies...And Heidi Klum, just to name a few. And we'd be crazy not to reference the glutes queen, Jen Selter! She basically became famous for her derriere. It even landed her a spread in Vogue.

But you don't have to be a fitness pro or a celeb to get belfie ready. Nope! If you want to post a pic of your posterior for all your friends, teachers, co-workers and future bosses to see... some salons offer a booty beauty service. Like at The Gloss in New York - they offer butt facials! With their "Shiney Hiney" facial, you can let someone get all up in that for 30 minutes to exfoliate, cleanse and steam your butt. Awesome.
