heavy metals and crazy reality TV star Ozzy Osbourne canceled a show in Reno, Nevada, on Sunday night due to "sudden illness," said concert promoter.
"Based on advice from doctors, it is very unfortunate that the Ozzy Osbourne ... postpone his show at the Reno Event Center," by Chris Martinez with Live Nation said in a statement. "Multi-Platinum Rock and Roll Hall of Fame can not be done ... a sudden illness."
The statement did not detail what ailed Osbourne.
The concert has been postponed until April.
The 62-year-old rocker sings occasionally with his band Black Sabbath, has a solo career and is in the middle of the leg of his U.S. tour Scream, which will also take in Latin America and Europe.
Osbourne won a new generation of fans in the last decade with their MTV hit reality show "The Osbournes", which often need subtitles to understand the working class Birmingham, England accent.
Osbourne has sold nearly 29 million albums as a soloist of the Recording Industry Association of America. He is best known for his hit "Crazy Train", "Flying High Again" and "Mama, I'm Coming Home".
During this week's Super Bowl Osbourne will appear in a TV commercial with teen idol Justin Bieber.
