The 'Alejandro' singer is hoping to be ordained in California following the state's rejection of legislation banning gay marriages.
Heat says that the 24-year-old has already taken an online course and is preparing to complete paperwork to become a fully qualified minister.
GaGa has previously vocalised her opposition to Proposition 8, which ruled against same-sex unions in California. After the state law was overturned on August 4, GaGa told her Twitter followers that the event had inspired her to write music.
She wrote: "BUBBLE DREAMS FOREVER! FULL EQUALITY! THIS IS JUST THE BEGINNING!"
