Actress Diana Alouise hasn’t seen Mel Gibson‘s movie “The Passion of the Christ” — but she knows all about the passion of Mel Gibson!

Diana, who had a months-long affair with the married actor, told The ENQUIRER in a world exclusive interview: “We drank like fish and made love more than 20 times. He never mentioned God or religion.”

In the issue that goes on sale Friday, Diana — who passed a polygraph test — tells how she and Mel had sex the first night they met, what he said about his wife, how he’s since turned his life around … and more.
