Kim Richards -- Dogged with ANOTHER Lawsuit Over Pitbull

EXCLUSIVE

Kim Richards has been sued again over yet another pit bull attack at her home.

Kelly Crossley claims in a new lawsuit, she was at Kim's home last September when Kingsley the pit viciously got a piece of her. Crossley claims in the lawsuit, obtained by TMZ, she suffered "grave bodily injuries."

It's the 4th alleged attack at the mouth of Kingsley. Kim's friend, 80-year-old Kay Rozario, Kyle Richards' daughter Alexia and the dog's trainer David Utter all say they were attacked by the pooch.

In Crossley's case, she says in her lawsuit Kim disavowed ownership of Kingsley, claiming the dog was owned by her cancer-ridden ex-husband Monty.

Crossley is suing for unspecified damages.
