Rockers Black Sabbath are planning to record their last album and embark on a final tour next year (15).

The hitmakers reunited in 2012 for a series of gigs and released a well-received new album, titled 13, last year (13).

Guitarist Tony Iommi hinted the group could again reunite for another tour following their performance at London's Hyde Park in July (14), and now frontman Ozzy Osbourne has revealed the band is hoping to head back into the studio next year (15).

He tells Classic Rock magazine, "The whole Sabbath experience this time around was great. We all made friends, we didn't f**k around, we all knew that we had a job to do, and we did it. It was a lot of fun. So we're going to do one more album, and a final tour.

"Once the dust settled after the last tour, we started discussing the idea, because we were getting asked about it all the time. I said to (manager/wife) Sharon, 'What's going on? Because if there's no more Sabbath I want to get on with my own thing again,' and she came back and said, 'Let me look into it.' Three weeks later I asked her about it again, and she said, 'Oh, I still have to talk to so and so...' and I said, 'Sharon, I ain't f**king 21 anymore; if we're going to do it, I want to do it before I'm 70! Time isn't on our side!' So she made the call and came back and said, 'Yeah, the record company wants another album.' I believe (producer) Rick Rubin is going to do it with us again."

"It'll be sooner rather than later. Obviously a lot of it is coming down to Tony's health; he's obviously got his cancer treatment. But we'll get onto it next year. I don't know if we'll be writing in England or L.A., but I'll fly to the f**king moon for it if I have to!"

Iommi was diagnosed with cancer shortly after the group reunited.
