Miss Popular: Jessica Alba is one of those girls who is undeniably, unarguably, ridiculously hot. But honestly, we could have died in '05. It was this glorious year Alba was seen as sexy swimmer Sam in Into the Blue and exotic dancer Nancy Callahan in Sin City.

The International Import: Vesper. Vesper Lynd. Eva Green's Bond girl in 2006's Casino Royale is one of our favorites because she gave James a run for his money. Entertainment Weekly agreed, voting her fourth best of all time. 

Honorable Mention: Halle Berry as Storm in X-Men: The Last Stand can  NOT be ignored. We didn't love the white wig, but the lovely lady in all leather? Worth mentioning!

The Tough Chic: No "sexiest countdown" would be complete if it didn't include Meghan Fox. We fell head over heels when we met her character Mikaela Banes in 2007's Transformers. And of course, last year's flick, Jennifer's Body was basically an homage to the sexy star. The movie wasn't so hot, the star on the other hand? OMG!

The Crazy Chic: You bet crazy can be sexy. Just watch Penelope Cruz in Vicky Cristina Barcelona. Besides winning our, ahem, hearts, Cruz won an Academy Award for her role. And while her chemistry with real-life boyfriend Javier Bardem was fine, it was her on-screen steaminess with Scarlett Johansson that was unforgettable.

The Newcomer: It says something if you can still look sexy when you're blue. Yes, we're talking about Hollywood's newest hottie, Zoe Saldana who as Neytiri in Avatar, managed to inspire even us to want to become beings from another planet.

The Future: Entourage's Emmanuelle Chriqui won Ask Men's top spot as sexiest woman. So it was only natural to give the young star a heads up. Don't forget to check out who we thought were sexiest in the earlier part of the decade. And for more great guy stuff, click here.
