Greyson Chance -- the YouTube sensation who hit it big by singing a stripped down, piano version of Lady Gaga's "Paparazzi" -- got to talk to his idol, all thanks to Ellen DeGeneres.
(Watch the original performance.)
After his viral video exploded online, Ellen contacted the kid to appear on her show -- and when he taped his appearance, he got a surprise, in-studio call from his "number one inspiration": Lady Gaga herself.
The conversation is adorable -- and we love how Greyson calls her "Ms. Gaga."
(See wild photos from Lady Gaga's concert.)
The full interview -- and a special performance -- airs today.
