We have no idea who Post Malone's girlfriend is. Maybe it's this mystery woman he was frolicking with during a yacht ride in St. Tropez last summer.

Maybe it's this girl, who might be the same girl on the boat.

For everyone confused. Someone found his girlfriends instagram and found these are the things she posts. Someone remade the account and reposted them after she deactivated. pic.twitter.com/Fhf0ZHWRj7

Whoever it is, Postie doesn't appreciate his fans messing with her.

to my REAL fans I love you to death, to the people trying to dig so fucking hard to try and get me to leave my girl, y’all ain’t real fans and it needs to stop. The past is the past and it has nothing to do with anything.have some respect. who gives a fuck? let us live our lives.

As for what she did in the past ... there's an Instagram page dedicated to the mystery girl's misdeeds. (Which don't seem so awful.)
