An American publication is reporting that Brad Pitt is going though a midlife crisis as he struggles to cope with raising four kids and being married to one of the hottest women on the planet, Angelina Jolie.

OK, sounds unlikely so far.

According to Star magazine, Brad is secretly indulging in his old vices behind his wife’s back.

An insider tells the mag: “He still smokes. He sneaks cigs behind Angie’s back.”

At the Cannes Film Festival in May he supposedly, “stayed outside, smoking and drinking,” says an onlooker.

“He looked stressed, like he was trying to get his fill because he had a limited time to enjoy his cigarettes.”

Another source tells Star that he spotted Brad smoking what looked like a joint with Jackass wild man Steve-O on a hot L.A. afternoon.

“I couldn’t believe that someone as famous as Brad Pitt would be smoking openly,” said the eyewitness. “But there he was, lighting up a fattie with Steve-O. I was stunned!”

Apparently Angie doesn’t approve of Brad’s ‘excesses.’

“She doesn’t think Brad should smoke pot or anything else,” says yet another insider.

“She wishes he’d drop all that. A drink once in a while is OK. But that’s it.”

Brad looked far from a man in the midst of a midlife crisis at last night's Critics' Choice Awards - unless you count the goatee.
