Ugh Selena, what are you doing?  Is this b/c you are back with Justin?  

TMZ has learned sources close to her said she axed her parents Mandy and Brian Teefey last month, permanently relieving them of all duties related to the management of her career. Selena's parents had managed her since her big break at Disney. Supposedly Selena feels she's outgrown her parents. She believes she's now old enough -- and famous enough -- to have a seasoned professional manager with other A-list clients.
