A 12-year-old boy who became a hit on YouTube with his rendition of Lady Gaga's Paparazzi has received a phone call from the quirky pop star.
Greyson Chance has had more than ten million hits for his piano rendition of the hit single.
He was appearing on Ellen DeGeneres' US chat show when Lady Gaga phoned in to wish him luck.
"Keep following your dreams and work really hard and stay away from girls and be focused!" she told him, adding that he was "so sweet and so talented".
"I was so excited that you covered Paparazzi."
