Happy birthday to the silver fox himself, Nathan Fillion! Can you believe this handsome hunk of a man is turning 54 today? It's like he's aging backwards and getting better with each passing year. And let's be real, his charm and wit only seem to increase as well. Here's to another year of slaying dragons and saving the world on screen, and being an all-around awesome human being off screen. Cheers to you, Nathan!
