Tiger Woods' porn star 'mistress' Devon James has been fired from her job as a "working girl" at Nevada's most famous brothel - because she opened her big fat mouth.

James, mistress number 20ish is still featured on the website for the world famous Bunny Ranch in Carson City, where owner Dennis Hoff confirmed Devon was employed as a sex worker for "a while."

But Hoff also told that he recently fired Devon's ass after she injected herself into the Woods media circus because she "broke the code-which is privacy and discretion with all clients."

"She is a disgusting excuse for a working girl ... she's a scumbag and a snitch," TMZ quoted Hoff as saying. (ANI)
