Now that we know Megan Fox is out of the next Transformers movie (regardless of whether it was her decision or Michael Bay's), the question on all of our minds is who will take her place as Sam Witwicky (Shia LaBeouf)'s love interest? Word on the street is that Prince of Persia leading lady Gemma Arterton is the top choice, with Vanessa Hudgens, Ashley Greene, and Amber Heard also being considered. Oh, and on the other side of the spectrum we've got Heidi Montag throwing her name into the ring. LaBeouf has some pretty great chemistry with Fox in the first two movies (though it's nothing compared to his relationship with real-life girlfriend Carey Mulligan), and we know that Bay is all about the eye candy. The movie will start filming soon, so who would you pick?
