Angelina Jolie has responded to reports she collapsed on the set of her new movie Salt, insisting the story is "not true".

The actress – who has been shooting the upcoming thriller in New York – was said to have fallen ill during filming, prompting rumours she is suffering from exhaustion as a result of her hectic lifestyle coupled with a restricted diet.

Britain's Now magazine claimed that filming "got too much for Angelina. She collapsed between takes, complaining of shortness of breath and dizzy spells.

But movie bosses deny the health scare stories.

A rep for Sony - the studio behind the film - tells UsWeekly, "I can confirm that those rumours are in fact not true."

It's been alleged that Angelina is on a liquid diet in a bid to lose weight in super quick time so she can give a convincing performance as a man - one of her character's many disguises.
