1. Zac Efron and Vanessa Hudgens. They rode the little-TV-movie-that-could, High School Musical, to box office gold and worldwide fame in 2008. And they have perfect teeth. But their love cannot last post-HSM, as their careers pull them apart, forever. So appreciate them now, while their love burns with the heat of a million flashbulbs. Congrats to our Favorite Couple of 2008!
