Did Angelina Jolie collapses during the set of her movie SALT?

Angelina Jolie acted as spy Evelyn Salt in the movie Salt and there were rumors saying that she collapsed while filming.

Source said, "It all got too much for Angelina. She collapsed between takes, complaining of shortness of breath and dizzy spells".

"To be fair, it was after she'd filmed a strenuous scene in which she ran around the set, but it was still shocking to see her crumble".

Another source tells, "She never eats properly when she's upset. Food is the last thing on her mind. She'll ignore breakfast, pick at lunch and skip dinner.”

There were words saying that Jolie was on a liquid to lose 21Ibs in 21 days so she can give a convincing performance as a man.
