Festival's artistic director Alberto Barbera revealed Lady Gaga's emotional moment in 2018.
Lady Gaga was in the rain and refused to get into the theatre. He recalled, 'Lady Gaga refused to get into the theatre because she wanted to keep signing autographs for her fans'.
'When she came to my office to dry and redo her makeup, she was shaking. I said, "But you must be used to it, you have huge concerts with thousands of people".
Gaga responded, 'Yes, but this is my first time as an actress, and I feel like a debutante".
'I put my arm around her shoulders and took her into the theatre. At the end of the film, she was crying'.
