Happy 37th birthday to the rockstar queen Hayley Williams! It's hard to believe that our favorite Paramore lead singer is another year older, but we know that age is just a number when it comes to her badassery. May your special day be filled with the perfect balance of headbanging and relaxation. Keep on shining and rocking out like the timeless legend you are. Here's to another year of killer music and even cooler hair colors. Cheers to Hayley on her 37th trip around the sun!
