Pitt, 45 and 34-year-old Jolie, who raise six children together, looked a picture-perfect couple as they stepped out for a meal at the Dolce Vita restaurant in Beverly Hills.

Jolie, in a mustard yellow silk top and black parachute trousers, was all smiles while Pitt, sporting a grey jacket, black T-shirt and jeans, kept a firm grip on her hand as they made their way into the eaterie, the Daily Mail reported.

Their body language was a far cry from their behaviour just two weeks ago when they attended the Museum of Contemporary Art's new 30th anniversary exhibition in Los Angeles, when they appeared cold and distant from one another.

But the night out raised some eyebrows as it coincided with the release of the new tell-all book on the couple that claims to lift the lid on the ups and downs in their relationship.

Halperin alledges that Brad and Angelina's relationship has hit the rocks on many occasions and that their public displays of affection are merely an act.
