'Insular' Jolie sparks concern

Producers on Angelina Jolie's forthcoming film have reportedly had to have a "discreet word" with the star due to her dramatic weight loss.

According to the Mail On Sunday, the mother-of-six has been working 15-hour days while filming the espionage thriller Salt, is doing all her own stunts, and is apparently on a liquid-only detox diet.

Brad Pitt, 45, who moved the family to New York to be closer to Jolie during filming, is also said to be concerned about his partner's fatigue and diminished size.

Sources said the couple have barely been able to see each other and it has been claimed that Jolie, 33, is living alone at New York’s Waldorf Astoria Hotel while Pitt and their children are renting a house nearby.

An insider said: "Brad and the kids have barely visited the set and Angelina seems very insular. She's staying on her own, working 15-hour days and the stress is taking its toll. We're all very concerned.

"She is looking so small on camera, the producers have had to have a discreet word."

The Tomb Raider siren recently said that her first priority was her family, adding that she was the "happiest mummy" being able to balance her film work with family life.
