During a new interview with Rolling Stone UK, Ozzy Osbourne slammed Black Sabbath’s bandmate, Geezer Butler, for not showing him support during his ongoing health battles.

Here’s what Ozzy Osbourne said:

”Tony Iommi has been so supportive of me since my illness. Geezer Butler hasn’t given me one f*cking phone call. Not one f**king call.

“When his son was f**king born, I phoned him every f**king night even though we were at war with each other, Black Sabbath and me (after I was out of the band). I thought, ‘F*ck it, he’s my mate. I’m gonna call him.’ But from him, not one f**king call.

“It’s sad, man. We all grew up together, and he can’t pick up the f**king phone like a man and see how I’m doing. Even Bill Ward has been in touch with me. I said some things about Bill, and I don’t know why I said it, but when I came through my illness, he contacted me.

“I’m not in shock. I’m just very f**king sad that he can’t just call me after all this time and say, ‘How you doing?’ F**king a**ehole.”
