Ozzy Ozbourne can probably collaborate with any rock artist he wants at this point, just by asking.  However, the one singer with whom he'd like to sing a duet right now is pop superstar Adele .

Speaking to Australia's Rip It Up publication, Ozzy notes that the new Black Sabbath album was overseen by legendary producer Rick Rubin , who's worked with Adele.  "If this is anywhere near as successful as the Adele album I’ll be happy!” says Ozzy, referring to Adele's award-winning, multi-platinum album 21 .  When the publication suggests that Rubin might be able to hook the heavy metal madman up with an Adele collaboration, he was thrilled at the idea.

“I’d die a happy man. I think she’s f**king great," Ozzy says, adding that he admires Adele because "she’s not f**king botox-faced. She’s a normal, healthy girl who speaks in her native accent.”
