Watch this - it's amazing:

Junior schoolboy Greyson Michael Chance is thought to be only 11 or 12 years old, and his rendition of the song Paparazzi by Lady Gaga is just amazing.

Greyson writes on his YouTube profile: "I am very inspired by Lady Gaga and Augustana. Lady Gaga is a freak but she has so much talent and her style of music is what I would like mine to be when im older."

People have been comparing it to Justin Bieber. Not sure if that's really a good comparison.

The video went viral like mad, and the next day he was on show Ellen, where he got to talk to Lady Gaga over the phone, and will be on the show again next Wednesday.
