The 'Born This Way' singer told Australia's Sunday Telegraph that despite pictures of her wearing a ring on her wedding finger, she is married to her music instead.
"I always say that my music is my husband," she explained. "It is my absolute life and soul. I wake up in the morning with tears in my eyes and I get inspired to write new songs.
"I was born to make music and I was born to perform."
GaGa, who is currently in Australia with her 'Born This Way Ball' tour, recently announced that she is finalising tracks for her as-yet-untitled third studio album.
"My next baby is my next album," she said. "It keeps me very excited and busy because I have lots of new ideas.
"Every moment of every day I am dreaming up new music, dreaming up ways of making my tour and stage more extravagant and beautiful than ever before.
"I just want to keep going. I'm not as goal obsessed as I am process obsessed. I have lots of thing to do, but in truth, I feel like I'm the most alive when I'm on stage."
Despite recently appearing on The Simpsons and revealing plans to release a fragrance last year, GaGa also said that she is completely focused on her music for the time being.
"I just don't identify with that web-like approach where you are a singer who suddenly starts to do everything," she added.
"I am a musician so I am a musician right now."
