AceShowbiz - Lady GaGa fears she'll struggle to let go of Patrizia Reggiani after spending months researching and portraying her for new movie, "House of Gucci".

The "Poker Face" star played the Italian socialite, who was convicted of hiring a hitman to kill her ex-husband, Maurizio Gucci, and GaGa admits she's finding it tough to move on now the film has wrapped.

"I would say that in terms of letting the character go, I don't know that I'd ever let her go," the pop star told Sky News, revealing she also had trouble shaking the Ally Maine character she created for 2018's "A Star Is Born".

"It took me years to shed Ally from 'A Star Is Born', and I think the same will be true here."

GaGa also admitted she really connected with the character of Patrizia while researching the role, "To say that it would be easy to play a murderer would be a lie. I don't believe she had the murder gene, but I do believe that she was triggered and pushed so far over the edge that she committed this murder."

Meanwhile, GaGa recently revealed she left no stone unturned in her preparation for the role, likening her approach to that of an investigative journalist and revealing that it took six months to master Patrizia's accent.

GaGa explained, "A lot of people don't know this, but when she married Mauricio Gucci, his entire family had turned their back on him, so she didn't marry for money. And when he was murdered, also they were divorced. So there was nothing financially at stake for her when all of this took place, which I found fascinating as a woman because I thought, 'Oh well, then it's because she was hurt. Then it's because it was love.' "

"So I spent a lot of time... I spent six months working on the accent and also delving like a journalist into her life and into their lives to see what were the moments that she was hurt, not included, traumatized... and how then did this make motivation for murder."
