“X Factor” contestant Astro is blasting off into the next phase of his career. The 15-year-old hip-hop sensation has inked a deal with Epic Records.

The Brooklyn-born MC, born Brian Bradley, will unite with his mentor L.A. Reid at Epic, where he will join his fellow “X Factor” alum including Chris Rene, Marcus Canty, and winner Melanie Amaro.

Astro captivated the attention of America following his 10-week run on Simon Cowell’s singing competition. As the only contestant to write new material each week, Astro thrilled with his versions of Eminem’s “Lose Yourself,” Naughty by Nature’s “Hip Hop Hooray,” and Missy Elliott’s “Get Ur Freak On.”

“I’m excited to continue my journey with L.A. Reid and his staff at the new Epic Records,” said Astro, also known as the Astronomical Kid. “The first time L.A. saw me he said I’d be a star, and I can’t wait to get to work and prove him right. 2011 was Dope, but 2012 is gonna be Epic!”

Although he’s been rapping since the age of 10, Astro first burst onto the scene a few years ago with his original song “Stop Looking at My Mom,” which became a viral sensation.
