Olivia Munn Vs. Jennie Garth: Bikini Awards Semifinals Will Test Your Loyalty

Of the many lessons we're learning during the 2013 Bikini Awards, the latest is this: Don't underestimate the power of the geek vote. That is our educated guess as to how Attack of the Show vet Olivia Munn edged out bikini model Claudia Romani in the last round of voting. After that tough victory, will Olivia's fans have the strength to stand up against the nostalgia power of Jennie Garth supporters? Here's hoping they've been icing their "refresh" fingers (just as Olivia's icing her shoulder after "swinggate"). Angela Simmons learned the hard way what a tough competitor Jennie can be.

We're glad we're not in your position, because we'd have a really tough time choosing between the 90210 MILF and the sexy Newsroom smartypants. But we're sure you'll manage. Voting ends on Sunday, August 25, at 11 pm ET.
