LAdy Gaga got Lady Gaga's stage name when the music producer Rob Fusari compared Gaga's vocal style to that of Freddie Mercury and took the name 'Gaga' from the Queen song, "Radio Ga-Ga". It was Fusari that helped Lady Gaga to write some of her early hits, including "Disco Heaven", "Dirty Ice Cream" and "Beautiful, Dirty, Rich".
