Brad Pitt: Relapse Fears Over Showbiz Deaths

Brad Pitt has been facing his addictions while struggling through his brutal divorce from Angelina Jolie — but two showbiz deaths have friends fearing he'll fall off the wagon!

Brad — who recently insisted in an interview, "I'm not suicidal" — was longtime friends with rocker Chris Cornell, who was found hanged in his Detroit hotel room after a final show with his band Soundgarden. Brad and Chris had socialized together with their children, and they regularly attended each other's concerts and premieres. Brad was also close to studio executive Brad Grey, who died just days before Chris after a private battle with cancer.

"He is devastated and in shock," a source told E! News. "He is trying to process the loss of two great friends. This has hit him very hard." The star is also dealing with the death of his close friends just as he commits himself to regular meetings with Alcoholics Anonymous.

The National ENQUIRER had the worldwide exclusive in Feb. when Brad went into treatment for his addiction issues. A source said at the time that the troubled star had spent $15,000 on a five-night retreat inside a private suite at Casa Del Mar in Santa Monica, and attended a Narcotics Anonymous party on Jan. 22. Brad also now quietly attending AA meetings in celeb- studded Malibu.

An insider told The ENQUIRER: “He recently attended a men’s group that meets on the Pacific Coast Highway. He sits in the back with his cap pulled down, as if he doesn’t want to draw attention to himself. He hasn’t shared his story yet, but he’s [been] friendly to anyone who’s approached him to wish him luck. He’s very gracious and will simply say thank you.”

Insiders add that Brad is also spending a massive amount of money to stay sober — which will hopefully inspire him to work through his grief over the deaths of his close pals. "He says it’s saved his life," an insider told The ENQUIRER, "and it’s a small price to pay if it makes him a more focused and kinder person!”
