So, belfies—or the butt selfie—is a trend on social media now.
We actually like the #belfie (it's soo much better than the #AfterSex selfie), because it gives us more reason to work out and take our squats seriously! So here, we rounded up the best butt selfies on Instagram, courtesy of your favorite celebs (looking at you, Kim Kardashian!).
Now get those yoga pants ready, because we're doing this booty workout right now.
