It's a true blessing when your favorite celebrities grow more attractive with age — ahem, Jason Momoa. Sure, the Hawaiian heartthrob has always been a cutie, but somewhere between the early 2000s and today, he blossomed into the embodiment of masculine sexiness.

Journey back with us over almost two decades of Jason Momoa's good looks, and you'll come to believe that men really can age like fine wine. Aren't we lucky?
