Black Sabbath legend Ozzy Osbourne recently appeared on Chicago's WGN to promote Sabbath's new album '13.' Along with speaking about the disc, Ozzy discussed becoming a grandfather, singing during the 7th inning stretch at Wrigley Field and the overdose death of 'Glee' star Cory Monteith.

Before '13,' no Black Sabbath album had never hit the No. 1 spot in the Billboard Top 200 chart. "My wife said to me before it was released - 'Is there anything that you wished you'd (achieved)?' I have Grammys, all kinds of platinum awards, but I've never had a No. 1," says Ozzy. "And lo and behold it happened and it rounded off things nicely. If this is the last Black Sabbath album - and I don't really think so - I can rest my head and think that it ended on a very up note. My career has been nothing short of amazing."

As the interview moved on to the topic of Cory Monteith's death, Ozzy offered some advice from the perspective of an addict. "I went through all that and I survived, but you know what? I haven't got that many friends who I used to do it with that are still alive; they're all dead," shares Ozzy. "I'm living on borrowed time. Don't think that if Ozzy Osbourne can stay alive through it, that you'll do it, because it didn't work like that … I used to think that I couldn't write songs or perform without a drug or a drink inside me and that's just a load of crap. You don't need alcohol and you don't need drugs to make music and have fun … in recent months, I had another go at it and it nearly destroyed me again."

Ozzy also made the rounds to Boston news network NECN, where he clarified both the past and current state of his marriage. "We were never going to break up, you know, she was just pissed off," says Ozzy. "Everyone was making it much more of a big deal than it was."

Black Sabbath are set to embark on a comprehensive North American tour beginning on July 25 in Houston, Texas and finishing up in Los Angeles on Sept. 3.
