Let's make this birthday one to remember.

45 years old (Born on January 17, 1980)

Happy birthday, Maksim Chmerkovskiy! May your day be filled with more spins and twirls than a Dancing With the Stars finale. You've dazzled us season after season—whether it's your fiery Paso Doble or that unforgettable freestyle routine, you always leave audiences breathless (and occasionally dizzy).

Here's hoping this year brings even greater success—and fewer wardrobe malfunctions! Keep charming us all with those smooth moves and witty comebacks; you're proof that age is just a number...though we suspect yours might actually decrease each time you hit the dance floor. Cheers to another fabulous spin around life's ballroom stage!
