If Hollywood really is like high school, then Zac Efron
and Vanessa Hudgens
are the king and queen of the prom. Not only are the High School Musical 3
stars reigning over the box office—the film nabbed $42 million its first weekend—the duo also whipped up an awesome afterparty: They jetted to Hawaii for a romantic getaway and a pal's wedding.
Efron, 21, and Hudgens, 19, began dating in early HSM
days in 2005, and their relationship strengthens by the year. Says HSM
director Kenny Ortega: "The chemistry they have has grown big-time."
