GUILHERME MARCHI, 29
WHY HE'S HOT: He's hunky but humble
Brazil native Marchi entered bull riding by following in his older brother's footsteps at age 15. Since then, he's taken home the 2008 PBR World Championship and earned the nickname "Hollywood" for his movie-star good looks. The down-to-earth family man follows a simple philosophy when it comes to his sport: "I give a lot of my heart and my blood and try my best all the time," he says.

SHANE PROCTOR, 26
WHY HE'S HOT: He looks great naked!
"My mom made me ride with a helmet since I first started getting on and I have rode with one ever since," says the superstitious Proctor, who began competing at age 16. His natural talent helped him earn a college rodeo scholarship, and his sexy physique scored him a very nude spot in ESPN The Magazine's 2009 Body Issue.

SEAN WILLINGHAM, 30
WHY HE'S HOT: He's a fighter
Though he became the youngest-ever winner of the American Cowboy Association bull-riding event at 16, an injury forced Willingham to defer from joining PBR and accept a college rodeo scholarship instead. But the newlywed, who wore his cowboy hat at his reception (natch!), never lost sight of his goal, turning pro in 2003 and proving his favorite quote true: "Say I won't … and I will."

COLBY YATES, 30
WHY HE'S HOT: He can carry a tune
A devoted husband to wife Katie and father to son Cutter James, Yates is also a man of many talents. In 2011, he was crowned the Dickies Iron Cowboy champion and also showed off his vocal skills by releasing a country album, Right Amount of Renegade, in October. OK, you can start swooning!

J.B. MAUNEY, 25
WHY HE'S HOT: He's got stamina
The North Carolina native may seem easy-going, but he's not to be taken lightly. Mauney became the first rider in history to stay on all eight of his bulls (for the required eight seconds) at the 2009 World Finals, netting $343,000 in the process. "I feel like when I show up … there's not a bull here that can throw me off," he says.

LUKE SNYDER, 29
WHY HE'S HOT: He's tough but tender
Snyder was a force to be reckoned with from an early age on the PBR circuit, being named Rookie of the Year at 18 and competing as a World Finals Champion. But the hard-bodied rider is as sweet as he is tough, proposing to his girlfriend under the Rockefeller Center Christmas tree this past holiday season and always taking time out to respond to his fans on his Facebook page.

SILVANO ALVES, 24
WHY HE'S HOT: He was born to wear black leather
Alves learned the sport from his father and grandfather back home on his family's small ranch in Brazil, and it appears they taught him well: He was crowned the 2011 World Champion in October, just one year after being named PBR's Rookie of the Year.

DOUGLAS DUNCAN, 24
WHY HE'S HOT: He's no dummy
"I would ride anything when I was a kid – the dog, the couch, even my grandpa," the Texas native told the New York Daily News of how he got his start. But while he makes no apologies about coveting a bull-riding championship, Duncan is simultaneously chasing another dream: He's completing his bachelor's degree in agriculture business from Sam Houston State University.
