Ozzy Osbourne says Black Sabbath's final LP and tour will happen in 2016.

The 66-year-old rocker has confirmed the legendary heavy metal group will bring their career - spanning over 40 years - to an end next year after giving fans one more chance to see them play live.

Speaking at the Monsters of Rock press conference in São Paulo, Brazil, he said: ''The plan is that next year (is the) final Black Sabbath tour and album. It could change.''

Although Sabbath - also comprised of Tony Iommi and Geezer Butler - are going to stop, Ozzy is going to continue with his solo career because being a musician keeps him feeling ''really young''.

Ozzy - who is married to Sharon Osbourne - said: ''Being in the music business keeps me really young. When you hit 60, people ask, 'Are you gonna retire?' F**k no, man.''

The singer also explained the reason why the band have taken so long to make their latest record - the follow-up to 2013's comeback LP '13'.

He explained:''We all live in different countries and some of them want to work and some of them don't want to, I believe.''
