Lady Gaga’s real name is Stefani Joanne Angelina Germanotta.
She took on the name “Lady Gaga” from the Queen song, “Radio Ga Ga”
Her former mentor & lover, Rob Fusari accidentally gave her the nickname through a spelling error in a text message.
While texting the soon-to-be-Gaga, Rob typed in “Radio GaGa” and the spell checker on his phone automatically changed it to “Lady Gaga”, after reading the message; Stefani thought it was perfect… And from that day the world would call her by one name. Lady Gaga.
