This week's Babe of the Week voting is some of the toughest competition we've seen. Who are you rooting for?

Monroe is one of the most stunning redheads we've ever seen, Shima's curves render us unable to form complete sentences, and Kristen Lynn is holding a whip, so enough said. The fact remains, though: only one of these dames can be named Babe of the Week, and go on to fight for the title of Babe of the Month. Please, help.

Here’s the deal: At the end of the week, each Babe of the Day will compete for your votes and the winner will become Babe of the Week. Each week’s winner will then face off to become Babe of the Month, and those winners will then duke it out for – you guessed it – the Babe of the Year title. Only those lucky ladies will be inducted into GuySpeed’s Hall of Fame, an honor reserved for the hottest of babes.
