Hollywood is the best place on earth for role models. Don't believe me? Just look at Britney, Lindsay, and Paris. They've been doling out great advice on fashion, drug awareness, and hygien for quite some time. And now, Sienna Miller is getting in on the act, with her very special dieting tip.

So what is Sienna's top diet tips for little ladies? Well, according to PR Inside, it's Vodka!

Sienna Miller adopted a vodka diet to help her achieve a size zero frame for her role in Factory Girl.

The Casanova beauty plays Andy Warhol muse Edie Sedgwick in the new film, and had to slim her naturally svelte figure down even more to play the late junkie.

She says, "I decided to drink vodka instead of wine because it has fewer calories."

That's some great advice, ladies. Cut those calories wherever you can, and if you drink enough Vodka, you'll probably end up puking out what few other calories you did consume that day. So, win-win!
