In 2008, the singer was one of a number of musicians who sang for Led Zeppelin's Jimmy Page, John Paul Jones and Jason Bonham when they were looking for a frontman to replace Robert Plant.

Speaking in the new issue of Rolling Stone, Tyler admitted he was interested in the role before realising that he couldn't leave Aerosmith.

"I decided, 'Well, I know that I'm mad at those [Aerosmith] guys, but I'm not that mad'," he said.

"So I called Jimmy up after I left, two weeks later, and said, 'You're in a classic band, and so is mine, and I just can't do that to my guys, and I can't do it to Robert [Plant],' and I couldn't see finding a year to really put myself into it."

He added: "So for whatever the band thought, never in a million years was I going to quit Aerosmith to start Zeppelin."

Alter Bridge frontman Myles Kennedy also reportedly auditioned to replace Plant, who ruled out any more performance after the band's 2007 reunion gig.
