Justin Timberlake is apparently the mystery collaborator who features on the new Foo Fighters record Concrete and Gold.

Frontman Dave Grohl revealed that that the actor and pop star often hung out with the band in between their respective recording sessions at EastWest studios in LA.

"We'd drink whiskey in the parking lot," he told Rolling Stone. "He was really, really cool. Then the night before his last day, he says: 'Can I sing on your record? I don't want to push it, but - I just want to be able to tell my friends."

Grohl has teased the collaboration as far back as June, telling BBC Radio 1 that the "world's biggest pop star" sang backup on one of the heaviest songs on the album.

He then added to Rolling Stone in July that the mystery artist was "more than [just a pop star]".

"I'd be amazed if anyone can really figure it out," he said. "But it was great and this person's been around a long time. And I think I've met this person maybe a few times, but I'd never spent time with this person, and we had a blast together. Really f***ing fun.

"And [he or she] is very talented - more so than I ever knew. But, of course, I f***ing ran my mouth off; now I have to answer to it every time I pick up the telephone and I'm like: 'F***! I shouldn't have said anything."

Also appearing in a cameo role on the album is Paul McCartney, who plays drums on one of the tracks.

"Even if it had been banjo, I think I probably would have showed up," he told Rolling Stone.

Concrete and Gold, the new Foo Fighters album, is out on 15 September.
