Someone's trying to win her back!

Justin Bieber and Selena Gomez haven't been together for a while now, but it seems the Canadian pop star is trying to get back in the brunette beauty's good graces by praising her on Instagram!

"Most elegant princess in the world," he captioned a snapshot of the Spring Breakers star at last night's Vanity Fair Oscar bash.

Considering the "Come & Get It" singer had to check-in to rehab in January for a reported addiction to her former beau, amongst other issues, we think JB should stop pulling her in a million different directions emotionally!

Knowing him, the hip hop bad boy will be hooking up with a new groupie before the week is over!
