Happy 78th birthday to the one and only Dolly Parton! Can you believe this country queen has graced the world with her presence for almost 8 decades? We sure can't! From "Jolene" to "9 to 5," you have given us countless timeless hits and plenty of hair inspiration along the way. Cheers to many more years of big hair, bright rhinestones, and infectious southern charm. Keep shining bright like a diamond, Dolly!
