We can't even believe that the one and only Pharrell Williams turns 41 today.

Of course we can't get enough of his music -- we're playing "Happy" on repeat and jamming to some of his throwback collaborations, because "Beautiful" with Snoop Dogg will never not be one of our favorite songs.

But if there's one thing you can't deny when talking about Pharrell, it's his awesome fashion sense. If you didn't hear about his infamous hat from the Grammy Awards, you must be living under a rock.

In celebration of Pharrell's birthday, here are some of his outfits that prove he's one of the coolest celebrities in the fashion game (and that he's had a couple of hat phases).

And, watch the promo for Saturday Night Live above, featuring Anna Kendrick with the birthday boy, which airs tonight.
