3. Robert Pattinson and Kristen Stewart, ‘Twilight’
Like you didn’t see this pick coming. Pattinson and Stewart have crazy chemistry, but as Edward and Bella, they spend the first three movies unable to go all the way for fear of turning Bella into a blood sucker. Thankfully for them (and us), they give in to their desires in “Breaking Dawn.” Expect all hell to break loose, in a good way.
