PopUps: Out Athlete Gus Kenworthy Bares His Butt On Instagram

Ever since coming out last year, Olympic athlete Gus Kenworthy hasn't been shy about showing off his rockin' bod on social media. Just last month Kenworthy and his boyfriend, actor Matthew Wilkas, posted a number of shirtless selfies on Instagram while vacationing in Hawaii.

But Kenworthy took things to a new level - a Bieber level, specifically - by taking to Instagram Thursday to post a slightly NSFW pic of his backside.

In the pic, the athlete is standing in an open field as golden sunlight shines over his body. There's also a group of kangaroos in front of him, which may seem odd but Kenworthy tagged himself in Gold Coast, Australia.

"I know I said no more kangaroo pictures butt I changed my mind," he captioned the photo, which currently has more than 19,000 likes.

Kenworthy has apparently been Down Under for the last few days. Check out those pics, along with his naughty pic below. (You may want to look sooner than later since Instagram has a strict "no nudes" policy.)
