He's at the top of his pro skateboarding game, has his own clothing and footwear line, and at 18 years old, Ryan Sheckler even stars in his own TV series, 'Life of Ryan.'

His dreamy blue eyes and ramp skills are enough to make the ladies swoon, but if you really adore this California boy, then you should be able to ace this 10-question quiz about the sports star. Let's see how you score!

He may only be 18 years old, but this action sports heartthrob has built an empire from his skateboarding skills and persona, which has been served to MTV viewers in the form of his reality show, 'Life of Ryan.' "I think of myself as a skateboarder first and a guy on TV second," he tells USA Today.

No stranger to the ear-piercing shrieks of adoring girls, the pro skater says he not only takes the hysteria in stride, but also uses it to perform. "I can tell you that not a day goes by when [the screaming] doesn't happen," Ryan says. "I love the crowds, and the screaming just makes me skate better."
