The 'Marry the Night' singer is currently on her 'Born This Way Ball' tour, and gave the brief tidbit while performing in Perth yesterday (July 8).
During an interlude, GaGa addressed the crowd: "Let's just say I feel, I feel that when I wrote Born This Way, I demonstrated a sense of maturity.
"And I feel that, on the next album, there's a lack of maturity, it's a tremendous lack of maturity or sense of responsibility."
The 26-year-old performer then launched into her controversial new song 'Princess Die'.
Last month, GaGa announced that she will reveal more details on her upcoming album in September.
