Brad Pitt And Angelina Jolie Increase Security

Brad Pitt and Angelina Jolie have opted for maximum security and privacy by raising the walls surrounding their Berlin bunker.

Their fortress has been renovated so the couple and their children can feel more secure - especially Angelina, who is said to be feeling fragile after giving birth to twins.

It was reported last month that the mum-of-six – who recently stepped back into the spotlight – has become consumed by fears that her brood will be the subject of a kidnap attempt.

As well as a towering perimeter, the family's Berlin refuge also has a boat dock, a private chef, a helicopter pad.

Brad and Angelina are living in Berlin while the Fight Club star films scenes for Quentin Tarantino's latest project Inglorious Bastards.
