Success. They're only in their early '20s, but Zac and Vanessa both reportedly made around $3 million for High School Musical 3. Add that to the fact that Efron is starring in more movies (like 17 Again) and Hudgens has released two solo albums, and these kids are on the road to the big bucks. Below, watch how it all began.
Attractiveness. No matter what you think of High School Musical, you have to admit that Zac and Vanessa are the cutest new couple on the scene. Her glossy waves and cute figure are a perfect complement to his ripped abs and mile-long eyelashes (see beach photo below for clarification).
Popularity. Last month, 4 million people searched Google for details on both Efron and Hudgens, enough to put them in the top 10 of our most popular couples. Not that you needed the statistics to know that: High School Musical has become a cultural phenomenon, boosting the star power of these young actors.

Compatibility. According to the stars, these two have huge potential for long-term success. Zac's a Libra, and Vanessa is a Sagittarius, so they're both charming and social. As long as Zac doesn't get too clingy and Vanessa doesn't shy away from commitment, they could enjoy a happy future together. Since the stars never lie, Zac must be playing it cool for the tabloids -- he's totally whipped.
