Worst Best Looking Actress?

With Into the Blue opening today, I thought it might be fun to pose the following question: who is the worst-acting yet best-looking actress ever? Which actresses can't act their way out of a paper bag, yet keep getting work based solely on their looks? Who's the worst historically, and who's the worst still working today? Only answers about females, please. I don't want to hear about how hot Paul Walker is...

I'm not even sure what my answer would be, there's just too many choices. Katie Holmes is cute, and I haven't seen her give a worthwhile performance yet. I think the award would have to go to Tara Reid. She is smokin' hot, but good-golly it's hard to watch her on film. She should stick to doing Maxim shoots every once and a while, but retire from the movie business...
