Ozzy Osbourne will be honoured as a legend at this year's Kerrang! rock awards.
The 62-year-old will be given the prize at a ceremony in London on 9 June.
The singer is also playing a show in the capital in the same month to mark the rock magazine's 30th anniversary.
He said: "It's an incredible honour to be the second recipient of Kerrang's legend award. I'm looking forward to you going crazy at the 30th Anniversary on 21 June in Hammersmith."
Ozzy Osbourne rose to fame with heavy metal band Black Sabbath before starting a solo career in 1980.
His 10th studio album, Scream, was released last year.
He also starred in a reality show about his family for MTV which also featured wife Sharon, son Jack and one of his daughters Kelly.
'Prince of Darkness'
Kerrang! editor Nichola Browne said: "We are so unbelievably excited to have Ozzy play this very special show for our 30th birthday celebrations in June.
"We are privileged that the Prince of Darkness can help us mark this momentous milestone in style and it's guaranteed to be a night to remember.
"Ozzy has been the mainstay of rock music.
"During his long and colourful career, he's not only helped define heavy metal as the voice of Black Sabbath, he's also enjoyed a three-decade reign as a solo artist and inspired thousands of rock fans to go crazy during his unmissable live shows.
"He's a much-loved, larger-than-life personality, and it is only fitting that we will be honouring Ozzy with the prestigious Legend Award at this year's Kerrang! awards."
After widely-publicised drug and alcohol problems, the singer launched the Ozzfest in the 1990s and released his autobiography, I Am Ozzy in 2009.
The Kerrang! awards, voted for by readers, will be hosted by Slipknot frontman Corey Taylor and Anthrax and The Damned Things guitarist Scott Ian.
