The polls for Round 2 closed earlier, and our top seeds had a pretty easy time dispatching their challengers -- except for one upset generated by all you giant-alien-robot fans. Our quest to crown the Summer's Sexiest Woman has now reached its semifinal stage. Here's a rundown of what happened yesterday (see Round 1 here):

• Sure, Natalie Portman may have walked away from 'Black Swan' with an Oscar (and a fiance and a baby), but she was no match for her co-star Mila Kunis, who took their matchup by a score of 63 percent to 36 percent. (For some strange reason, a third, blank option turned up in our poll and, even stranger, 1 percent of you voted for that. Huh?)

Jessica Alba had an even easier time with her Round 2 opponent, Zoe Saldana, defeating her 68–32. What gives, 'Avatar' fans? We had expected that one to be a bit closer, but hey, it's up to you guys, and apparently you guys think Miss Alba is really, really pretty. Which is, you know, true.

• In our biggest upset so far, the Women of 'Transformers' took down the Women of 'X-Men' in a nail-biter, 52–48. With the likes of Halle Berry, January Jones, Rebecca Romijn, Jennifer Lawrence, Famke Janssen, Kelly Hu and many more, we figured the mutant ladies would coast into the semis. But Megan Fox and Rosie Huntington-Whiteley would have none of it. Shia Lebeouf, you are a lucky man.

• The final Round 2 contest saw Olivia Wilde trounce Rosario Dawson, breaking the 70 percent barrier in the process. Don't feel too bad, Rosario, we still love you. Olivia looks to be on the warpath here, though. We're quite interested to see how she fares in her upcoming bout. Speaking of which ...

With Rounds 1 and 2 in the books, let's take a look at our semifinal matchups, shall we?

Hard to believe one of these two gorgeous women won't be in the Championship Round, but hey, that's democracy. Mila's star has been rising for some time now, with her string of stunning photoshoots and hit movies including this summer's 'Friends With Benefits,' last winter's 'Black Swan' and going back to fan-favorite 'Forgetting Sarah Marshall' in 2008. Jessica's 'Spy Kids 4' wasn't exactly a hit, but her fans don't seem to care. It appears her eye-catching work in 'Sin City' and 'Into the Blue' have created a lifetime of goodwill, and to be honest, we have no problem with that. Good luck choosing between these two, voters. We'll be fine either way.


So, there we have Olivia in a bikini and the 'Transformers' stars doing the whole trench-coat/lingerie combo. Like the Mila-Jessica matchup above, we're just happy we don't have to choose here. It seems almost unfair that it's a two-on-one fight, but Olivia was a No. 1 seed for a reason, and anyone who's followed her work through the years on TV's 'House,' through 2006's 'Alpha Dog' and 2010's sci-fi hit 'TRON: Legacy' knows she can hold her own with anyone in the utterly-stunning-beauty department. Can Rosie and Megan pull off another upset? Would it even really be an upset? Who cares? Vote!


Check back tomorrow for the Championship Round!
