she was constently a trouble maker and they asked her to leave the show.
Reportedly, the reason for her departure was because of on-set and off-set tensions between Doherty and co-star Alyssa Milano. According to several sources, Doherty approached Paramount executives and asked to be released from her contract. Essentially she told them something like 'This is getting too problematic. Just let me go'. She didn't want to be the bad ogress again (like when she got canned from 90210). She wanted to exit gracefully but the studio wouldn't have it. They pretty much told her, 'No, you cannot leave. We will sue you for breach of contract'. They reversed course though during the summer hiatus and informed her lawyer that they were giving her a pink-slip while she was off filming a movie.No one's officially saying why Doherty was ultimately cut loose, but a series insider told TV Guide, "It eventually became clear that [either Doherty or Milano] had to go." Doherty seemed to be the safer choice since Alyssa Milano was just as popular, if not more so and they had already seen that when Shannen left 90210, the series still did just fine.
