“Borat” wanted to see Rebel Wilson naked. The Australian actress said that Sacha Baron Cohen was so adamant to see her in the buff for their film “Grimsby.”

She revealed to the “Kyle and Jackie O” radio show on Thursday that the British actor had been pestering her to do a nude scene, and when she thought he finally relented to her clothed appearance, he suggested for her to do a more shocking scene.

“Sacha is so outrageous,” the 28-year-old NSW local said. “Every single day he’s like, ‘Rebel, can you just go naked in this scene?’ And I’m like, ‘No!’ Sacha and I have the same agent in America and I’m like, ‘Sacha, I’m going to call our agent Sharon and tell her how much you are harassing me.’

“Everyday he’s like, ‘Just go naked, it will be funny. Remember in Borat when I did the naked scene? It was hilarious.”

Wilson thought she had won when Baron Cohen opted to hire a body double for her naked scenes instead. However, that wasn’t the end of it.

“Then in the last scene … he was like, ‘Rebel can you just stick your finger up my butt?’” she recalled. “And he’s like, ‘Look, I’ll just pull down my pants, you just stick your finger up my butt, it’ll be a really funny bit.’”

Wilson did not want to do it, so she offered to meet the 42-year-old actor halfway instead.

“You don’t wanna be a diva so I … said I’ll slap you once on the butt and that’s it.”

Wilson also talked about the late Robin Williams, her co-star in the film “Night at the Museum: Secret of the Tomb.” In the film, the third “Night at the Museum” instalment, Williams reprised his role as Theodore Roosevelt, while Wilson plays a British security guard.

“He watched me in a scene with Ben Stiller and called me over to his trailer afterwards and he just said, ‘I think you’re such a great improviser and you’re so funny,” Wilson recalled of Williams, adding that she couldn’t believe that the illustrious comedian wanted to talk to her about comedy for two hours after watching her act.

“It was just, I couldn’t believe I got to have that time with him and how cool.”

When Williams was found dead in early August, the world mourned. Wilson was no exception. She was in tears when she watched one of the scenes in the movie wherein Roosevelt gives a speech before dying.

“It’s just so emotional because in the movie his character knows he’s not going to be alive the next day and he gives this speech and it was just me and my assistant Katie just sitting in this screening room just crying.

“It’s super, super emotional.”

“Night at the Museum: Secret of the Tomb” is set to be released in December.
