Dave Grohl has revealed another famous name who'll be appearing on the upcoming sixth Queens of the Stone Age album and we must admit, we didn't see this one coming.

Grohl, who will play drums on the album, revealed to US talk show host Chelsea Lately that Sir Elton John will join the likes of Jake Shears of Scissor Sisters and Trent Reznor on the new album from Josh Homme's band.

"Recently, Elton and I recorded something together", said Grohl. "Something that people wouldn't imagine the two of us doing together", before going on to say that the collaboration was indeed for the next QOTSA record.

This might all seem a little far-fetched to you but we assure you it's true. Sir Elton himself was quoted by NME as saying: "I was in Vegas and I flew back to LA and Engelbert Humerdicnck had written be a very sweet letter and asked me to sing a duet with him. He is part of my history and I couldn't say no so I went and recorded a song with him. Then I drove three block and went from Engelbert to Queens of the Stone Age, which was a bit of a mindfuck."

We don't know about you, but we're incredibly intrigued by the information coming out about this (as yet untitled) album, their first since 2007's incredible Era Vulgaris.
