Vanessa Hudgens felt an instant chemistry with High School Musical co-star and boyfriend Zac Efron - because he was so attractive.
The pair began dating after they appeared together in the first installment of the film franchise in 2006 - and Hudgens was immediately drawn to Efron's physical appearance.
She says, "The second I met him I thought he was a really cool guy. It's hard not to have chemistry with someone who is quite attractive."
And Hudgens reveals that they are always there for each other, even when they're not working on films together.
She adds, "We're both supportive of each other, but we're doing our own things, too. We have different projects we're working on."
