"He was and will continue to be a rock n roll legend," Cooper said in a statement, hours after Osbourne died on Tuesday.

Jack White, Metallica, Rob Zombie, Elton John and more paid tribute to Ozzy Osbourne after the Black Sabbath frontman died at 76 on Tuesday morning. Osbourne had been recovering from several spinal surgeries as well as his ongoing battle with Parkinson's disease.

The heavy metal icon has died at 76 after years of health struggles. His last show was just a few weeks ago and featured a special reunion for fans.

Osbourne died on Tuesday at 76, just weeks after he and Black Sabbath performed at their farewell Back to the Beginning concert earlier in July.
