Just when Justin Bieber thought he could singlehandedly claim the heart of every young girl on the planet, one YouTube video at a time, here comes Greyson Michael Chance with his own viral clip, a piano cover of Lady Gaga's "Paparazzi" that leaves his classmates speechless. 

Known by his YouTube handle Greyson97, the budding online sensation made his fellow sixth graders swoon with this rendition of Gaga's hit song. Chance rocks a Bieber-esque hairstyle in the video, but the similarity ends there.  "Paparazzi" isn't the only trick in Greyson97's bag, either. The 12-year-old also apparently writes his own material, and though the subject matter seems a bit mature for his age, it's not too shabby. Here's Greyson performing his original song, "Broken Hearts."
