Fall Out Boy guitarist has spoken frankly to US newspaper the New York Post about how he nearly killed himself during a drink and drugs binge.
The Fall Out Boys bassist confessed to playing Russian Roulette while being wasted.
"I pulled a trigger on a gun aimed at myself," he told the paper. "My friend and I did one pull each. We'd been drinking and had taken Ambien. I feel stupid even talking about it."
Wentz also told the paper he never wants to own a firearm.
"It's one of the reasons I've never owned a gun I'm too impulsive," he said. "I'd probably get mad and shoot someone over a part in a song or something."
Fall Out Boy's new album, Folie A Deux hits stores in the UK on November 3.
