Despite being a hugely successful rocker married to a sexy pop star, Wentz battled depression for a long time and came close to death twice, he says in a candid interview for Playboy's October issue.
Wentz, 29, also shared some good news: he and pregnant wife Ashlee Simpson-Wentz are fairly certain they'll be having a boy in November.
Wentz says his drinking and drugs led to dangerous activities. "I pulled a trigger on a gun aimed at myself" during a game of Russian Roulette, he says. "My friend and I did one pull each. We'd been drinking and had taken Ambien."
The musician, who says he has gone to therapists since he was 6, also says that "the list of drugs I've been prescribed would read like a grocery list."
Recalling a drug overdose, "I took a handful of Ativan," he says. "It had more to do with being depressed. I wasn't thinking of killing myself. I've never really called it a suicide attempt. I just wanted my head to be completely turned off."
Thanksgiving BabyWentz says wife Ashlee will give birth to the couple's first child around Thanksgiving. And while "we know with 90 percent accuracy that it's a boy," he says, the couple is still playing the name game – with some help from pals.
"My friend Andrew said, 'Your kid has to have a name that would fit either a rock star or a senator.' "
As for the possibility of having Dallas Cowboys quarterback Tony Romo – who is dating Ashlee's sister, Jessica Simpson – as a brother-in-law, Wentz says, "I like Tony a lot. He's a rad dude and we're both into Guns N Roses."
