Age: 21

YOU'VE SEEN HIM … Atop the Latin pop charts; as a teen crooner in the prime-time soap 90210.

UP NEXT: The coveted role of Drew Boley in the screen adaptation of Broadway's Rock of Ages, costarring Tom Cruise, Catherine Zeta-Jones, and Mary J. Blige; as original sinner Adam in Paradise Lost, with Bradley Cooper and Casey Affleck.

WILL BRAKE FOR FANS: "I was in Brazil after a concert. We were leaving the show at Maracanã Stadium, which was in front of 120,000 people, and all of a sudden the van stops. There were 10 fans lying down in front of the van saying, 'We're not moving unless we get an autograph and picture. If not, run over us!'"

A ROLE FOR THE AGES: "I remember it was a Thursday, and all of a sudden news leaks that I booked Rock of Ages, without me actually booking it. I'd never had a migraine in my life, and I get this migraine that lasts three days. I was like, 'If I don't get this, I'm gonna look like the biggest asshole.'"

Next stars: Max Thieriot, Miles Teller, and Tom Payne.
