NBC News says the former heavyweight champ-turned-Broadway star will sit down with Matt Lauer in Las Vegas for an interview airing tomorrow morning on Today. Mike Tyson surprised the heck out of the press last week when they showed up for what they thought was a news conference about his return to boxing as a promoter, and instead listened as he told them, “I’m a motherfucker” who has been lying for years about being sober. Sure to come up will be this statement at last Friday’s news conference cum confessional: “I’m a bad guy sometimes. I did a lot of bad things, and I want to be forgiven. … I wanna change my life, I wanna live a different life now. I wanna live my sober life. I don’t wanna die. I’m on the verge of dying because I’m a vicious alcoholic. Wow. God, this is some interesting stuff.”

Little more than a year ago, Tyson sat down for a Nightline interview with ABC News’ Terry Moran in which he claimed to have been sober three years. “I may have a good few years in me, but it’s still not out of me,” he said back then. “You still have to work consistently. Every moment of the day you have to work because your demons always — that’s who you are.”
