Branded as 'Brangelina', they have been hailed as Hollywood's perfect couple but it seems that Brad Pitt and Angelina Jolie's relationship has hit a rocky patch.
According to the sources on the set of Angelina's new film Salt, the shooting of the film is taking a toll on the actress as she has not met her partner and children for sometime though they have moved to New York to be near with her, the Daily Mail reported.
The 33-year-old actress is living alone at New York's Waldorf Astoria Hotel though 45-year-old Pitt has rented a house nearby with couple's six children.
Pitt and the movie producers are also concerned about Jolie's dramatic weight loss.
"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," a source told the newspaper.
"She's on a liquid detox diet to lose 21lb in 20 days. She is doing all the stunts herself and barely has time to eat. She is looking so small on camera, the producers have had to have a discreet word," the source added.
Jolie is playing a CIA agent accused of being a traitor in the the film.
