Vanessa is 'So Proud' of Zac

As screaming girls swooned over Zac Efron at the premiere of his new film, "Charlie St. Cloud," there was one girl they all envied: Efron's main boo, Vanessa Hudgens.

"I'm so proud, I'm over the moon," Hudgens gushed to "Extra" about her man. "I feel like I'm blushing right now."

"It means a lot, she's really been pretty inspirational for me," Efron gushed back. "Like tonight, um, I'm really nervous about the whole thing. She's keeping my nose down."
