Demi Lovato and Selena Gomez are fighting again.

Demi unfollowed Selena on Twitter after posting (then quickly deleting) an angry message that allegedly said, “Swimming away from the bulls*** bye b**ch”.

The two former BFFs have a long history of feuding, but at this point in her life, friends close to Demi say she doesn't need anymore of Selena's drama: the substance abuse and Justin Beiber.

During an interview last year, Demi said, “We’ve been through a lot together, we’ve had periods of times we here we grew apart and we just didn’t really talk."
