Lady Gaga telephoned a "sweet and talented" schoolboy to praise him for his cover of 'Paparazzi'.

The chart-topping pop star gave 12-year-old student Greyson Michael Chance - who has become an internet sensation after his rendition of the song became a YouTube hit - a surprise telephone call, where she encouraged him to avoid girls and work hard towards a singing career.

Greyson, who performed on 'The Ellen DeGeneres Show' yesterday (13.05.10), answered: "Hi, Miss Gaga."

The blonde beauty told him: "Greyson, you're so sweet and so talented, and I was so excited that you covered 'Paparazzi'. Everyone loves you so much. Just keep following your dreams and work really hard, and stay away from girls and be focused."

The video of Greyson - who also writes his own music - shows him effortlessly playing the piano and belting out his own version of the song on stage, as amazed school pals look on.

The clip has been viewed by over 10 million people on the video sharing website and thousands of fans have commented on the youngster's natural talent.

One wrote: "I got goose bumps listening to his voice. Very talented! Just beautiful."

Another said: "I was in total shock when I found out you were 12. Greyson, your voice is amazing! You have that rare tone of vocals that drives girls crazy."
