Black Sabbath’s iconic musician Ozzy Osbourne released his latest single named “Under The Graveyard” today and talked about his recent projects including Post Malone.

Ozzy admitted that, when the first time the project from Post Malone came to him, he asked that: “Who the f**k is Post Malone?!”

As you might remember, In 2010 Ozzy was the interview guest of A Different Spin with Mark Hoppus and used the exact same words for Justin Bieber.

Later on, Ozzy played in Best Buy Super Bowl Commercial with Justin together.

Here is his what Ozzy told via press release about Post Malone:

“This album was a gift from my higher power – it is proof to me that you should never give up.

It all started when Kelly [Osbourne] comes in and says, ‘Do you want to work on a Post Malone song?’ My first thing was, ‘Who the fuck is Post Malone?!‘ I went to Andrew’s [Watt] house and he said we will work really quick.

After we finished that song, he said, ‘Would you be interested in starting an album?’ I said, ‘That would be fucking great,’ but now I am thinking, ‘I don’t want to be working in a basement studio for six months!’

He continued:

“And in just a short time, we had the album done. Duff and Chad came in and we would go in and jam during the day and I would go work out the songs in the evenings.

I previously had said to Sharon I should be doing an album, but in the back of my mind I was going, ‘I haven’t got the fucking strength…’ but Andrew pulled it out of me. I really hope people listen to it and enjoy it because I put my heart and soul into this album.”
