"Brad's rarely home — and when he is, he can barely keep his eyes open," the source says. The situation is no better at work. "It's gotten so bad that George had a talk with him. During filming breaks Brad was practically falling asleep in his chair on the set of Ocean's 13, so George went over and stuck a straw up his nose as a practical joke, but Brad didn't flinch. Finally, George shook Brad and said, 'What's wrong with you?' Brad mumbled something about not sleeping the night before."

"He and Angie have enough to live comfortably for the next 200 years," says the source. "What Brad's work schedule boils down to is that perhaps he's unhappy at home and trying to drown himself in work. Maybe it's an escape for him. George knows about the Angie situation and told Brad that, for his own health, he needs to pull it together. George even offered Brad and Angie his villa in Italy for the holidays. Brad's response was a polite thank you, but no — as he doesn't know when he could make the time for it."

Meanwhile, Ashton Kutcher has revealed he is jealous of Brad Pitt's body.
The 28-year-old actor confessed he was left green with envy after his wife Demi Moore, 43, lusted after Brad in his epic film 'Troy'.
Ashton is quoted by TMZ as saying: "I went and saw 'Troy', I was with my wife and with a friend, and every time Brad came on he was like naked or whatever, they were like, 'Ohh', and I'm like, 'I'm right here, I'm sitting right next to you.'"
The 'Butterfly Effect' star was so jealous that he hired Brad's personal trainer to help him get in shape for his latest film, 'The Guardian', in which he plays a US coastguard.
Ashton said: "I knew this movie was coming up so I went out and hired Brad Pitt's trainer.
"I'm a pack-a-day smoker and I hadn't really worked out since high school, so it was tough, and I haven't kept up my training since the movie wrapped.
"I'm done. I'll train for the next one, it's fine, I'll run a little bit, I'll stay in shape, I can still do some pull-up's and I do some push-up's and stuff but it's just brutal. It's a full time job to keep yourself in that kind of shape, it's no joke."
