The job of a publicist is to keep his/her client in the news for positive reasons.

Due to her lack of PR sense, addiction to Tweeting and all-around insanity, Tila Tequila has made that impossible.

As  a result, Jessica Cohen has announced she's stopped representing the erratic reality star. In her statement announcing this decision, Cohen did not admit why:

"This is to inform you that I am no longer representing Tila Tequila as her publicist. Some matters need to remain private and away from media attention and due to recent events, I realized that we need to part ways while she deals with the loss of her fiancée. I will forward any remaining inquiries to her until the new publicist takes over."

Since the death of Casey Johnson (above, flipping off the world with Tila), Tequila has cursed at Johnson's friends and family; started her own record label; been accused of faking her relationship with the deceased heiress. And she won't stop Tweeting about it all!

You can imagine her classy response to Johnson's resignation. Tila wrote:

"If you wanted to mold or package me, you should have done that when I was 16 and might as well have me join the micky [sic] Mouse club too while you're at it, then take over all of your money when you grow up and have you tell people you're a virgin when you're not. Well that was pretty much it.  Her and I just wanted different things. I just wanted to stay true to who I really am."

Wait... Tila Tequila is not a virgin?!? Now we've heard everything.
