What is Lady Gagas real name and age and etc?

Lady Gaga's real name is Stefani Joanne Angelina Germanotta. She's born March 28, 1986 and is 23 years old. Ofcourse Gaga isn't her real name lol. It's her stage name. She got it when the music producer Rob Fusari compared her vocal style to that of Freddie Mercury and took the name 'Gaga' from the Queen song, "Radio Ga-Ga". It was Fusari who helped her to write some of her early hits, including "Disco Heaven", "Dirty Ice Cream" and "Beautiful, Dirty, Rich". Some think it's because of her last name, "Germanotta", and she connected the two last letters from it two times. But that was before we found out the truth. As far as I've gone trough and heard, her weight is around 9 stone and her height is 5' 1 (1.55 m). Hope I helped.
