Ozzy Osbourne and Elton John duet in new 'Ordinary Man'

"Ordinary Man" serves as the title track of Osbourne's forthcoming 12th studio album, which will arrive on February 21.

Ahead of the album release, Osbourne's wife, Sharon, teased the unexpected duet on her daytime chat show, "The Talk."

"There's new music, and it's great. He's got his friends playing on it. He's doing a song with Elton [John]. There's so much good stuff. Good things," she revealed without sharing further details about the collaboration at the time.

The former Black Sabbath frontman has now unveiled his too-good-to-be-true duet with Elton John, who accompanies him on the soaring ballad on piano.

"When I was writing 'Ordinary Man,' it reminded me of an old Elton song and I said to Sharon, 'I wonder if he would sing on it?' We asked and lo and behold, he agreed and sings and play piano on the song," Osbourne recalled in a statement.

John is not the only musician who collaborated with Osbourne for "Ordinary Man," which will mark his first album in a decade.

Post Malone, Slash, and Rage Against the Machine's Tom Morello contributed to the forthcoming album, which was recorded in Los Angeles with producer Andrew Watt, Gun N' Roses' bassist Duff McKagan and the Red Hot Chili Peppers' drummer Chad Smith.

"It was a lot of fun to do though it's a lot different from my other albums. We recorded it quickly, which I haven't done since the first Black Sabbath album. This made it a different process, which I actually enjoyed," Osbourne said of his latest studio effort in a statement.

So far the rocker has unveiled three singles from "Ordinary Man," including the album's title track, "Under the Graveyard" and the Slash-assisted "Straight To Hell."

Osbourne's new album is available for pre-order, with all physical copies of "Ordinary Man" coming with a unique code that will allow fans to enter a sweepstakes for a chance to win one of over 300 Ozzy prizes.
