Every time there's an issue between one of the teen stars and someone (in this case there's one between Justin and Selena). Their fans always make up some fake list of people who unfollowed the person they're against.
Reminds me of the time One Direction fans said Britney and Beyoncé unfollowed Perez Hilton because he said 1D would break up soon.
Erm, how ironic rihanna unfollowed justin. The one she should unfollow is chris though. Even though im not sure if she follow him in the first place.lol.
