The Black Sabbath singer said previously he couldn't "imagine anything better" than receiving the honour

An online campaign to get Ozzy Osbourne knighted has attracted over 21,000 signatures.

The campaign, being organised by 46-year-old fan Helen Maidiotis, states that the Black Sabbath frontman deserves the honour for his “significant contribution to the music industry”.

Her campaign page on causes.com reads: “I am campaigning for Ozzy Osbourne to receive a Knighthood, as he thoroughly deserves this honour not only for all his charity work but for all his years entertaining us and helping make a difference to peoples’ lives who have looked up to him for his strong will and determination to get through the many obstacles that he has come across and for that we thank you Ozzy! Helping to get him Knighted would be our gift to him.”

When asked about the campaign in a recent interview, Osbourne said: “I’ve heard about that. Getting knighted? I can’t imagine anything better…And my wife [Sharon] would become a Lady, which would be pretty cool. But I’m not gonna get upset if it doesn’t happen. I never thought I’d get further than Aston [in Birmingham, England, where he was born].”

Ozzy Osbourne will release a compilation of his greatest hits as a solo artist titled ‘Memoirs of a Madman’ on October 6. He is currently touring the world with Black Sabbath in support of their 2013 album ’13’.
