Natalie Portman dislocates her rib

London, (ANI): Actress Natalie Portman has revealed that she dislocated a rib on the set of her new movie Black Swan and that producers didn't have an on-site medic. The 29-year-old actress, who plays a ballerina in the Darren Aronofsky film, spent up to eight hours a day in dance training to make her portrayal believable.

“I injured a rib, I like dislocated a rib, it sort of went under another one, when you get lifted it just sort of went under. When I got injured I called the producer, I was like 'could you get the medic? I need an ice pack or something right now,'' and he was like, 'Oh, we don"t have a medic because it's super low budget"," the Sun quoted her as telling David Letterman.

“I have been working for like twenty years, I don't even think that''s legal. I was like before you take away a medic, take away my trailer and the next day I didn't have a trailer, I swear to God!" she added.

Natalie also informed she lost a fair bit of weight for the role. “The Darjeeling Limited star said, “I think I lost like 20 pounds, I mean I'm 5ft 3in so it was pretty extreme. I mean I am back at my healthy weight now, I like eating so I waited until the very end to do the diet part," she concluded.
