Video of Zac Efron on the Late Show With David Letterman

Zac Efron Is Still Sweet 17

This morning we got another peek at Zac Efron with his shirt off, but last night he was suited up to stop by the Late Show With David Letterman in NYC. Dave teased Zac about his huge female fan base while Zac gushed about how much fun he had hosting SNL last weekend. Zac's still got a jam-packed few days ahead, including the Hollywood premiere of 17 Again, but he seems ready to keep greeting all his screaming fans with a smile.
