London, March 24 (IANS) Hollywood star Angelina Jolie is causing concern on the sets of her new film ‘Salt’ with a new diet called liquid detox.

The ‘Tomb Raider’ actress aims to shed 21 pounds in just 21 days for her role in the film as a CIA officer unmasked as a Russian spy and she is raising eyebrows as everyone thinks she has a fantastic figure to lose, reports thesun.co.uk.

The diet – living on a mixture of lemon juice, cayenne pepper and maple syrup – is also leaving her weak.

‘She does all her own stunts but we worry she could injure herself due to the weight loss,’ said a source from the film’s unit.
