Zac Efron feels “awkward” next to his “stunning” girlfriend Vanessa Hudgens.

The 21-year-old actor revealed that even though he sometimes feels uncomfortable next to his High School Musical co-star Vanessa, she is the only person whom he doesn’t drive mad.

“Dating Vanessa makes many things much easier, because you understand each other without having to explain a lot,” he said.

“In terms of planning, I am very picky – worse than any woman. I drive everyone mad, except for Vanessa, she is always very understanding.”

“The only disadvantage is that she is always dressed so stunningly that I look awkward and stand out.”

Zac admitted that, while he knows Vanessa is the one for him, he has no plans to get married anytime soon.

“We definitely won’t be getting married anytime soon,” he said. “I definitely feel much too young. When I am going to get married it will happen at the age of 40 at the earliest.”
