It was Zac Efron’s goofy smile that first caught Vanessa Hudgens’s eye when they auditioned together for High School Musical. “He was adorable,” she told Glamour. “I mean, he wasn’t the guy that he is today. Like, he had a gap in his teeth. He doesn't have his gap anymore. I look at him, and I see a man." Despite Hudgens’s affection for his grin, Efron couldn’t stand his smile. “I got teased more about my gap than anything else," he lamented to People in 2007.
