The 'Alejandro' singer admits that despite previous claims the LP was complete, she has had flashes of inspiration since and has not been able to finish it.
She said: "I know I told everyone my album was done, but I can't stop writing. I might have to put out two records. I never stop writing. I'm always in the studio and always writing."
The 24-year-old New Yorker also claims she will not be reinventing herself in the future, but will continue to evolve as a person.
She told Ryan Seacrest on his KIIS FM radio show: "Well I do think I will be... I am Gaga. It's kind of like if your parents have nicknames for you. My nickname is Gaga. But I am ever reinventing.
"I am ever changing. I don't know. I don't reinvent from album to album, I reinvent from day to day, to song to song, from video to video. It's quite chaotic! But my fans understand that because they relate to that chaos in themselves."
