Selena Gomez teases new song in Instagram video.

In light of her upcoming sixth album, Selena Gomez teased everyone with an Instagram video of herself in the studio, working on her new music, which gives me total Lana Del Rey vibes...

Until Gomez releases further information on her album, we'll just have to enjoy 'Kill Em With Kindness' - which has been confirmed as the fourth single from her latest album, 'Revival'.
