UFC® 100 is going down this Saturday night and while there will be some mega-beatdowns to watch inside the Octagon, there will be an epic battle going on just hours before the show. Maxim and the UFC® have teamed up to offer a once-in-a-lifetime chance to one lucky girl: a contract as a UFC® Octagon girl™ and a chance to be featured in Maxim magazine and Maxim.com!

Here's the deal: You must be at the Mandalay Bay Convention Center in Las Vegas, Nevada on Saturday, July 11 and you have to be pre-registered to make sure you have a spot in the contest. We've already held live castings at Afterlife in Phoenix, Ivy in San Diego, and XIV in Los Angeles this past week, but we're still looking for a few good gals in Miami and Las Vegas. If you're in the area, here are the details:

In Miami:
Date: July 8, 2009
Venue: Mansion Nightclub (1235 Washington Ave, Miami, FL)
Time: 10 PM - 1 AM

In Las Vegas:
Date: July 10, 2009
Venue: Tao Beach (inside the Venetian Hotel 3355 Las Vegas Blvd., NV)
Time: 1 - 6 PM

If you can't make it to any of the casting calls, you can register for the search here. Remember, you MUST be able to attend the UFC® Fan Expo™ on July 11 to have a chance at winning. The event will feature UFC® fighters and Maxim editors selecting the winner in a runway-style pageant during the UFC Fan Expo™, so make sure to look your best! (The first round will be a "sporty" look, the second round will require a bikini.)

Guys: If you want in on the action, you can purchase tickets to the Fan Expo at UFCFanExpo.com. Tickets are priced at $30 for entry on July 10, $35 for July 11, or $50 for a two day pass.
