Lady Gaga was NOT messing around when it came to portraying Patrizia Reggiani in “House of Gucci.”

She went full method actor for the role of the famed murderess, and spoke in an accent 24/7 on and off-screen.

While appearing on the “Just for Variety” podcast Gaga said, “I was always Patrizia. I always spoke in my accent.”

“I was still living my life. I just lived it as her,” she explained. “I brought the darkness with me home because her life was dark.”

This darkness followed Gaga around for months while filming, so in order to alleviate the weight of it all she hired a medical professional during the final days of shooting.

“I had a psychiatric nurse with me towards the end of filming. I sort of felt like I had to. I felt that it was safer for me,” she admitted.

“I don’t think that any actor should push themselves to that limit,” she says. “And I ask myself all the time why I do that.”

Method acting can be tragic.

Heath Ledger tragically died after he took on the role of ‘The Joker’ in “The Dark Knight,” which is a role he went full-blown method actor for.
