It's been a huge year for social media in general, but Instagram really became one of the most popular platforms. There's nothing people like more than to look at photos of their favorite celebrities, and Instagram has become the best way for stars to share not only what they do in their everyday lives, but some of their sexiest photos as well.

From selfies to magazine photo shoots to almost completely naked shots, Instagram has become the place people go to post their hottest looks. The Kardashian-Jenner clan dominated Instagram in 2015 with some of the most liked photos of the year, while models used their pages to show off their sexy bodies with some of the most talked about photos of the year. Celebs like Amber Rose, Charlotte McKinney and Nicki Minaj went viral with their curves while Chrissy Teigen and Miley Cyrus worked hard to continuously try to free the nipple.

Even though Instagram has a very strict no nudity policy, these stars still did a damn good job at showing off a lot of skin while keeping their most private parts covered. As 2015 is quickly coming to an end, here are Headlines & Global News' picks for the sexiest NSFW celebrity Instagram photos of the year!
