heidifiresman.jpg Hills star Heidi Montag has fired Aiden Chase, the Malibu-based psychic whom she hired as her manager last week. Husband Spencer Pratt had previously been in charge of overseeing her career, and after a disagreement on the set of Just Go With It, Heidi gave Chase the boot too!

When Heidi was on the film's set on Monday, a source tells Us Weekly that the starlet was "horrified" when Chase showed and demanded "a significant portion of her Hills money." Montag's rep said, "Aiden had nothing to do with securing Heidi's role in the movie."

Is this just another PR stunt, or is Heidi really this clueless about her career?
