The 15-year-old rapping sensation known as Brian 'Astro' Bradley took on Eminem's 'Lose Yourself' and added his very own lyrics to the song, making for a memorable performance on the movie soundtrack edition of 'X Factor' tonight.

Prior to the performance, Astro was shown hanging out with actor Adam Sandler on a red carpet as part of an outing that was arranged for the remaining contestants. However, he was also depicted working diligently on penning his own verses to go along with the chorus of Eminem's '8 Mile' track 'Lose Yourself.'

Starting off with a hood over his eyes in tribute to Slim Shady's signature look, Astro delivered the tune with the skills of a veteran rhyme-slinger. The youngster even dropped a reference to the late boxing legend Joe Frazier, who passed away two days ago, and Heavy D, whose shocking death occurred just yesterday.

Astro is anything but a novelty act, and he certainly proved that he can spit rhymes with the big boys tonight. The judges were absolutely awestruck, giving him a standing ovation along with the audience.

Nicole Scherzinger said, "Honey, you are a champion tonight," while Paula Abdul told him "you're in a league all in your own."

Simon Cowell called him "incredibly creative," and L.A. Reid added, "I could not be more proud of you!"
