Melbourne, May 11 : Angelina Jolie has sparked fears among the crewmembers of her new movie `Salt' that she might be self-harming again.

The actress, whose relationship with partner Brad Pitt is suggested to be on the rocks, has reportedly been shutting herself away in her trailer most days.

A source says Jolie's behaviour has fuelled speculation that she may have starting cutting herself again, a habit the actress has admitted to in the past.

"Angie's been crying in her trailer most days and is barely eating. She keeps forgetting her lines and she's been shaking and staring into space," the Daily Telegraph quoted a movie insider as telling Britain's Now magazine.

"In fact, it's been so bad that some crew members have suspected she's using drugs, although that's out of the question. But the ones who know her realize it could be something much, much worse if she's self-harming.

"When she's at home she just about holds it together, but she stays up listening to the same song over and over and rarely sleeps," she added. (ANI)
