10. Kristen Stewart
The breakout female Web star of 2009's one-woman crusade against exposure to sunlight could end up saving countless tween lives.

9. Jessica Simpson
When was the last time you actually heard a Jessica Simpson song? Not that we're complaining.
8. Heidi Klum
Between squeezing out Seal pups, Klum was able to find the time to rescue the "Guitar Hero" ad campaign.

7. Britney Spears
Britney's like your crazy uncle whose antics used to annoy you until you realized you wouldn't have anything to talk about at family reunions if he weren't around. Also, like your crazy uncle, Britney loves to wear bikinis.
6. Miley Cyrus
Things we've learned from Miley Cyrus: Teenage girls will use their cell phones to take semi-nude or sexually suggestive pictures of themselves, and will sometimes even electronically message these photos to their friends or post them on Twitter. Damn, we were born about a decade too early.
5. Megan Fox
We tried our best. We outed her mutant thumbs. We got the Internet to rally around "A Day Without Megan Fox." But, in the end, Fox's flashy good looks and selective Tourette's proved too much.

4. Kim Kardashian
It's Kardashian over Fox, just like the results when we polled our readers on which of the two well-put-together ladies brings the hot on the more consistent basis.
3. Farrah Fawcett
Getting anal cancer and dying certainly isn't the recommended strategy for vaulting your name into the top three searched in all of femininity. But consider this a make-up for there not being an Internet in the '70s. Because if there had been, Fawcett, whom Asylum readers voted the all-time number one pin-up girl by an enormous margin, may have broken it.
2. Rihanna
People want to learn more about Rihanna simply because they like her music and admire her beauty and fashion sense. That's our story and we're sticking to it.
1. Mandy Moore
Yup, we were surprised too. But the numbers don't lie. Imagine that, the key to being the most popular woman on the Web over the last year was talent and class -- not taking off a top or falling off a table. We just got word that Satan is frantically searching his closet for a winter coat.
