Let's make this birthday one to remember.

39 years old (Born on May 17, 1985)

Happy Birthday, Derek Hough! May your day be filled with more spins and twirls than a Dancing With The Stars finale. You've dazzled us season after season—winning the Mirrorball Trophy six times is no small feat (though we're pretty sure you have enough trophies now to open up your own dance-themed coffee shop).

From breathtaking choreography that leaves audiences speechless, to those gravity-defying moves we still can't figure out how you pull off—you've truly danced into our hearts forever. Here's hoping this year brings even greater success—and fewer wardrobe malfunctions!

Keep dancing like nobody's watching...even though millions always are!
