The video for Judas sees the singer take on the Bible by portraying Mary Magdalene opposite actor Norman Reedus as Judas Iscariot, and Gibson admits she flinched at some of the ideas which were put forward in meetings about the promo.

She tells the Hollywood Reporter, "It went through several changes and late-night debates because at one point, there were two completely different views and I was like, 'Listen, I don't want lightning to strike me! I believe in the gospel and I'm not going there.'"

Gibson insists she would have quit if she didn't agree with the final version of the video, but she's happy with the way the footage turned out.

She adds, "Absolutely (I would have quit). I do believe God inspired and worked on everyone's heart, but yes. I would have been like, 'Good bye, I ain't doing it. No way.' But the place it came to is really magical. And she's dancing her face off."

The video has already come under fire from Catholic rights campaigners who have condemned Gaga's controversial use of religious imagery.
