Selena Gomez is full of surprises in 2017. Last year she took a 90-day hiatus from work and social media and then delivered a candid speech at the 2016 American Music Awards, telling fans, "I don’t want to see your bodies on Instagram. I want to see what’s in here." Now she's back to work, and kissing The Weeknd outside a moderately-priced restaurant with seemingly little concern for paparazzi, and baring her butt on Instagram to show off the classiest gold thong money can buy. Selena is BACK — literally, there's her whole bare back, in a January 12 photo posted by fashion photographer Mert Alas.

The photo is likely behind-the-scenes evidence of an upcoming fashion spread, and we'll likely soon find out. Check out Selena Gomez working gold hoops, a gold thong and nothing else below.
