Mensch had previously said that the band would tour with Plant replaced by a new singer – but in a new interview with Music Radar he says that the band is no more.
"Led Zeppelin are over," he said. "If you didn’t see them in 2007 [at the London O2 Arena], you missed them. It’s done. I can’t be any clearer than that."
He added: "They tried out a few singers (to replace Plant), but no one worked out. That was it. The whole thing is completely over now. There are absolutely no plans for them to continue. Zero.
"Frankly, I wish everybody would stop talking about it."
When asked if Page would be pursuing other musical projects instead of Led Zeppelin, he said, "Fucked if I know. I’m waiting to hear."
