The 37-year-old singer (born Stefani Joanne Angelina Germanotta) – who recently had a lawsuit thrown out over her dog-napping incident – made her feature film debut in 2018’s A Star Is Born, which she followed up with 2021’s House of Gucci.

Sher also served as the cinematographer on the 2019 Joker movie that landed Phoenix his Best Actor Oscar, confirming that he was, ‘100% in character all the time.’

He added that on the second day of filming, Phoenix approached him and apologized, ‘for being whatever like weird, I just need to stay (in character).’

Sher said that he told him not to worry about it at all and, ‘just do your thing,’ but with Stefani, he had never met her before the project and it was quite different.

‘Because, again, maybe it’s my philosophy of never trying to get in their space,’ Sher clarified.

‘And then I remember for like a week being like, “God I feel like we were disconnecting, not even connecting. We’re like on opposites,”‘ Sher said.

‘And I would say to my crew like, “Jesus I can’t crack it. I feel like she either hates me or we hate each other or there’s something weird going on here,”‘ Sher admitted.

‘Then the AD (assistant director) at one point said, “Oh you know Stef would like if you just called her Lee on set,”‘ Sher explained.

‘From that point on it was like our whole connection changed. I was like, OK cool, that’s all I needed to know.
