Ozzy Osbourne has announced a farewell world tour for 2018 that will run through 2020.
The first leg of the tour will cover South America and Europe with the final show taking place July 2 at the Meo Arena in Lisbon, Portugal.
Live Nation has said North American dates will be announced next year.
"People keep asking me when I'm retiring," Osbourne said in a statement. "This will be my final world tour, but I can't say I won't do some shows here and there."
Osbourne's longtime collaborators Zakk Wylde (guitar), Blasko (bass), Tommy Clufetos (drums) and Adam Wakeman (keyboards) will be joining him on the tour.
