The Bad Boy of the Ballroom is no longer a boy: Maksim Chmerkovskiy is 32! The most smoldering, most sassy, and most frequently shirtless pro on Dancing with the Stars pro, Maks was born on January 17, 1980 in Odessa, Ukraine, part of the former Soviet Union. (But remember — never call a Ukrainian "Russian"! They are most decidely not the same thing!) He took his first dance class when he was four, though at a young age he was much more interested in sports like soccer and swimming. A youthful skiing accident could have sidelined him indefinitely from all physical activities, but Maks fought to regain his strength, and lucky for ballroom dancing fans everywhere, his hard work paid off! His entire family, including his younger brother, fellow Dancing with the Stars pro Val Chmerkovskiy, moved to the United States where they struggled to make a living and to learn English. Like any classic American success story, Maks made it, and now he's Dancing with the Stars.
