Happy 38th birthday to the one and only Zac Efron! You may have turned another year older, but you still have that boyish charm and killer dance moves #foreveryoung. Can't believe it's been 14 years since High School Musical first came out, and yet you still manage to steal our hearts with each new role. Here's to hoping you continue to age like a fine wine, and that your upcoming projects are just as jaw-dropping as your abs. Have a fantastic day filled with laughter, cake, and maybe a little bit of singing and dancing. Cheers to another year of being the ultimate heartthrob!
