After being voted off tv show X-Factor lastnight, Astronomical "Astro" Kid (Brian Bradley) was just signed to Record Label, Roc-Nation.

Jay-Z, thirteen time grammy award winner, former CEO of Def Jam Recordings and founder of Roc-Nation said, " I first heard about this exciting new talent and decide to watch some of his performances. Jay-Z goes on to say, "Not only was I impressed with his performances, but to see the confidence he sang with, his lyrics and diction were on point."

We're told that Jigga is working HARD . . . to get Astro onto WILLOW SMITH'S new track.
