Fiance Angelina Jolie has given him a leave of absence from his father-husband duties to go on the rip - after dealing with the stress of her recent double mastectomy, reported Sun Online.
"Brad chose to get on the booze in France and Italy once Ange told him to take a break. She could tell he needed to let his hair down after a stressful few months, so told him to go and have a boozy week with his mates and get it out of his system," he said.
Pitt also travelled to George Clooney's villa in Italy to stay for three nights.
