Rebel Wilson was once kidnapped at gunpoint in Africa

Appearing on 'Straight Talking', she told host Ant Middleton: "There was one time in Africa where I got kidnapped. These men come on another truck with a lot of guns."

When asked by Middleton if the men had pulled up their car alongside the car Wilson was in, she said: "Yeah, with the big guns, and were like, 'You've got to get off your truck.' They took us to this house in the middle of nowhere."

Rebel told her friends to link arms to stop the men from taking one of them in the night but none of them were harmed.

She recalled: "They sat us down. I said, 'Everybody link arms. I'm petrified in the night they might want to take one of the girls or something. Luckily, we weren't harmed."

The group was then released the next morning but the 'Pitch Perfect' actress assumed they had used the girls to smuggled contraband across the border.

She explained: "They came and said, 'Oh, your truck is ready now you can go - go, go,' you know. So we just didn't ask any questions, we got back on that truck and just got back out of there and then crossed the South African border a few hours later. I think maybe those guys used us to smuggle illegal things in the bottom of the truck."

Meanwhile, Rebel has undergone a dramatic body transformation after shedding 40lbs over the last year and she admitted she piled on the pounds because she didn't love herself "in the right way".

She said: "I wasn't loving myself in the way that I should from 20 to 40 – that's 20 years. "I feel so sad that I did that to myself, just not loving yourself in the right way."
