Rebel Wilson enjoyed learning to "drop it low" for the dance routines in Pitch Perfect.
The movie is about an all-girl singing group who battle against their male counterparts and the Australian star was delighted to be involved. She has a background in musical theatre so had no problem with the singing aspect, while some lessons helped her get to grips with the choreography too.
"We had a session on dancing a bit like a stripper. That taught me some moves and a few other things, like just trying to loosen it up a bit," she told Heat magazine. "It was about dropping it low a lot and shaking your ass and not bending the wrong way because then you hurt your back. I would have lost weight, except for the fact we would go out for dinner at the end of the day and shovel our faces with Southern food."
The 27-year-old star's portrayal of Fat Amy won her a Critics' Choice and MTV Movie Awards nomination. That was one of the most exciting things for Rebel, as she has long held ambitions of winning an Oscar.
It was actually her love of the Academy Awards which made Rebel move into acting.
"I had malaria really badly and I hallucinated that I was an actress and I was so good that I was at the Oscars and I won, and instead of giving an acceptance speech I gave an acceptance rap, which the crowd seemed to really like," she recalled.
"It was so vivid and people though I was mental when i came out of the hospital and I started saying, 'I think that was kind of a sign. I think I am supposed to be an actress now,' and people just thought I was nuts. But now I have to [win an Oscar] because then I would do a rap, to fulfil the destiny."
