Fall Out Boy rocker Pete Wentz once played Russian Roulette during a drink and drugs binge.

The singer, who is expecting his first child with wife Ashlee Simpson, played the life-or-death game with a pal - but admits he felt stupid for doing it.

He tells Playboy magazine, "I pulled a trigger on a gun aimed at myself. My friend and I did one pull each. We'd been drinking and had taken (sedative) Ambien."

"I feel stupid even talking about it. It's one of the reasons I've never owned a gun - I'm too impulsive.

"I'd probably get mad and shoot someone over a part in a song or something."
