Carey Hart, Motocross

Straddling a motorbike, he played himself in the 2003 blockbuster Charlie's Angels: Full Throttle. But he's been speeding toward the spotlight since age four. He began with a dirt bike and a dream in his hometown of Las Vegas. His father built motorcross courses, helping Carey turn pro at 17. Up-and-coming motocross athletes are doing their best to imitate his famous "Hart Breaker," the unbelievable back flip he performed at the 2000 Gravity Games. A fierce competitor, he's a regular at the X Games and keeps adding astounding stunts to his repertoire. Carey admits to being tired of broken bones as a result of his perilous competitions; after an accident preparing for the 2001 X Games, he had a metal plate and eight screws inserted in his shoulder. He's also known for his famous on-again/off-again rock star girlfriend, Pink, who he met at a motocross competition in his hometown.
