"Hi Miss Gaga!" Chance, touted as the next Justin Bieber, said to Lady Gaga on the pre-taped show, which aired on Thursday, to which she replied: "It's so nice to meet you. It's so funny, I'm lying in bed here with my mom, taking a break, and they said, 'Ellen's going to call you.'"
"Greyson, you're so sweet and so talented and I was so excited that you covered 'Paparazzi' and everyone loves you so much," Lady Gaga said on the talk program. "So just keep following your dreams and work really hard and stay away from girls and be focused."
Chance's YouTube video of himself singing and performing "Paparazzi" on a piano at a sixth grade talent show at Cheyenne Middle School in Edmond, Oklahoma has garnered more than eight million hits since he posted it on the Web site two weeks ago.
The video went viral several days ago when large news outlets reported about it, prompting producers of The Ellen Degeneres Show to invite him to Los Angeles to appear and perform the song on the program.
"I was sitting in math class and I got a text from my mom and she said, 'Call me ASAP.' So the first thing in my mind is, 'Dang it, what did I do now?'" Chance told Degeneres. "I remember just coming home and then my mom saying, 'Pack, because we're flying out to LA. And this was my first flight, so I was very scared."
Chance said he had studied piano for three years but has never taken voice lessons. He has also penned two original songs - "Stars", about a "wife who dies of cancer and she goes into the stars" and "Broken Hearts," which is about two girls he knows.
"Look what's happening to you now - now they're sorry," Degeneres said. Chance called Lady Gaga his "number one inspiration" and touted the individuality of the singer, known for her eclectic fashion sense and music videos.
