2015 has been a big year for Halsey.

Throughout the year, the New Jersey-born, New York-bred pop artist toured with The Weeknd and Imagine Dragons, released her debut album Badlands, peaked at No. 2 on the Billboard 200, was featured on a track with Justin Bieber ("The Feeling"), and sold out a 2016 tour stop at none other than Madison Square Garden. Not bad for an "emerging" artist, amirite?

Another indicator of Halsey's success and growing fanbase though? Her Instagram account, which currently boasts an impressive 1.5 million followers (as of December 2015, anyway). While it's no surprise that fans are flocking to the "New Americana" singer's Instagram, something tells us it's not necessarily the music that keeps them coming back.

Instead it probably has something to do with the super sexy, empowering photos the curvy singer-songwriter posts on the daily, many of which feature skin, skin, and more skin. (No wonder Playboy decided to feature her in their December issue.)

Between proclamations of "MOM" and "Slayyyy queen," the comments on Halsey's Instagram posts are brimming with revelations from fans like "Halsey is the reason I question my sexuality." (Yes, it would seem as though the girl's selfie game is that strong.)

To cap off the bad-ass babe's killer breakout year, we've painstakingly hand-selected a collection of Halsey's absolute hottest Instagram snaps for you to peruse. Why? Because somebody's gotta do the tough jobs.

You're welcome.
