7 Divorce theories doing the rounds

Brad's 'affair' with Marion Cotillard Apparently, Angie had hired a private eye, who uncovered an affair that Brad had with his Allied co-star, Marion Cotillard, who is 12 years younger than him. Reportedly, he not only fooled around with her on the sets, but the two were also cosying up for months during the filming of World War II.

his flirtatious behaviourIt's not just his affair, Angie was not too fond of his constant partying or being surrounded by Russian hookers on the sets of his film. He was also reportedly close to his co-star Lizzy Caplan and liked the company of one of their children's nannies. While reports suggest Angie was 'intensely jealous' because of Brad's flirtatious behaviour, we think she was just fed up.

Parenting differencesAngie quite didn't approve of Brad's style of parenting. In fact, the

actor

had admitted that he was tougher on the children. In November last year, he told a mag, 'I am (the disciplinarian) with the boys. Girls do no wrong, so I don't have to be.' However, after she filed for

divorce

, the actress' manager said, 'Angelina will always do what's in the best interest of taking care of her children.'

Drug abuse and anger issuesIt is reported that Angie was upset about Brad's substance abuse and possible alcohol addiction. Coupled with anger issues, she saw this becoming a danger to their children, especially when he was under the influence.

Brad chooses friends over family Reports say that Brad's refusal to spend the last few weeks of summer with his family was the last nail in the coffin. Instead of holing up with his wife and children, Brad travelled to Croatia with some of his guy friends. So what if his visit to the Mediterranean country could have been in association with the resort he's building over there!

Jolie doesn't take care of herselfAfter her mastectomy and surgeries to remove her ovaries, the actress supposedly didn't take care of herself. And this put off Brad. He was quoted as saying that his wife barely eats, but guzzles wine every night and smokes constantly. A report suggested that Brad was exhausted spending so much energy trying to get her to take better care of herself. Sources say it was hard for him to watch the woman he loves waste away.

Brad blurted out Gwyneth's name in his sleepThis is way too bizarre, but some reports suggest that Angie was upset because Brad apparently mentioned Gwyneth Paltrow's name in his sleep one night. What's interesting is that Gwyneth and Brad were a number, but that was way back in 1997.

Meanwhile...
For the last one year, Brad and Angelina have hardly lived together. While Brad's constantly travelling, Angie stays home with the kids. Friends have long been predicting that divorce was on the cards. Their last outing together as a couple was to a cafe in Los Angeles, where they celebrated the birthday of their twins. They followed it up with another quick visit to a local juice centre, where they were spotted cuddling.
