There are many reasons to follow Bella Thorne on Instagram, but number one on the list may be her mastery of the belfie.
No, that's not a term for a Bella-selfie - it's what the young folk call it when you post a picture of your own butt. It's an art form that was made famous by the Kardashians, but as you can see, it's been perfected by Bella.
We probably don't need to tell you that that's a photo of Bella sporting some leather pants.
In fact, you've probably stopped reading this, and we really don't blame you.
But for those of you who are interested in the history and motivation behind Bella's belfies (That's a combination of "butt" and "selfie," by the way. "Bulfie" just doesn't have a very good ring to it.), please join us in an intellectual exploration of Instagram's most famous ass.
Bella turned 18 last year, and like Kylie Jenner before her, she quickly began posting racier pics to her page.
For obvious reasons, the strategy had paid off, and Bella recently reached the 10 million followers milestone.
Also for pretty obvious reasons, Bella is fond of shots in which she's facing away from the camera.
Sometimes, she offers a reason for the day's belfie, such as last week's "Transformation Tuesday."
Other times, she just puts on a bikini and takes a photo of her butt.
In both cases, we're sure she receives very few complaints.
We hope you've learned something today, and we hope you'll join us for the next installment in our Bella Belfies series.
Come for the ass, stay for the education!
