Here's the deal: Each day, we'll post two girls and you vote on who is hotter. The girl with the most votes wins and moves on to face a different girl the next day. If a girl wins five days in a row, she'll be inducted into the Smokin' Showdown Hall of Fame. Voting ends at midnight.

Donna Lazarescu is on a three-day win streak, which means she only needs two more wins to be the inaugural member of the Smokin' Showdown Hall of Fame. She's already beaten Ciara Price, Sara Jean Underwood and Heather Knox -- all premier Playboy Playmates. A fourth win won't come easy, because she'll have to do it against the new face of the Sports Illustrated Swimsuit Edition, Kate Upton.

The contestants (Twitter links are NSFW):

Above on the left, Donna Lazarescu (@deerescu) -- and don't ask us how to pronounce her last name -- is a commercial model in California who will gladly show off her assets to promote any sort of business. She's a Bud Light girl, among many other things.

Kate Upton (@KateUpton), on the right, doesn't need much of an introduction. She's one of the most beautiful women in the world, and -- still a teenager -- is the cover model for SI's Swimsuit Edition. You can see the cover here.

Now, they need your votes!

After you vote, be sure and follow them on Twitter -- and follow us, too, @96XRocks!
