Ozzy Osbourne, English singer-songwriter
John Michael "Ozzy" Osbourne (born 3 December 1948) is an English singer, songwriter, and television personality. He rose to prominence during the 1970s as the lead vocalist of the heavy metal band Black Sabbath, during which period he adopted the nickname "Prince of Darkness".Osbourne was fired from Black Sabbath in 1979 due to alcohol and drug problems, but went on to have a successful solo career, releasing 12 studio albums, the first seven of which received multi-platinum certifications in the US. Osbourne has since reunited with Black Sabbath on several occasions. He rejoined in 1997 and helped record the group's final studio album, 13 (2013), before they embarked on a farewell tour that ended with a February 2017 performance in their hometown, Birmingham. His longevity and success have earned him the informal title "Godfather of Metal".Osbourne's total album sales from his years in Black Sabbath, combined with his solo work, are over 100 million. He was inducted into the Rock and Roll Hall of Fame as a member of Black Sabbath and into the UK Music Hall of Fame as a solo artist and as a member of the band. He has been honoured with stars on the Hollywood Walk of Fame and Birmingham Walk of Stars. At the 2014 MTV Europe Music Awards, he received the Global Icon Award. In 2015, Osbourne received the Ivor Novello Award for Lifetime Achievement from the British Academy of Songwriters, Composers and Authors.

In the early 2000s, Osbourne became a reality television star, appearing as himself in the MTV reality show The Osbournes alongside wife and manager Sharon and two of their three children, Kelly and Jack. He co-stars with Jack and Kelly in the television series Ozzy & Jack's World Detour. The show's third season debuted in June 2018.
