Shannen Doherty is a real toughie and doesn't mind a good scrap. If one believes the tabloids, Shannen has been in a lot of Hollywood girl fights and always seems to come out on top. Jenny is probably the favored choice here; but, despite her size advantage, if this became a ground fight, Shannen would beat her boobs off.
At the moment it looks, like Shannon vs. Jenny would really become the final, what I would see so, too (but would there probably vote for Jenny in a really close one). Here I have voted for the toughie Shannen against the cutie Ashley, because it was not possible to vote for both Jenny and Shannon.
