Tyler 'takes over from Plant'

Led Zeppelin are reportedly lining up a megastar replacement for singer Robert Plant - they have been jamming with Aerosmith frontman Steven Tyler.

Fans of the legendary rock band have speculated there will be a world tour since they reunited for a one-off show last December.

Singer Plant has frequently denied the band is to hit the road for a string of gigs, but rumours the other three members - Jimmy Page, John Paul Jones, and Jason Bonham - have been rehearsing together have sent gossips into a spin.

Now the comeback looks to be a step closer to reality - with reports suggesting Tyler has taken over vocal duties during practice sessions in London.

A source told 'The Mail on Sunday': "Steve was jamming with Zep. They had a great time but Steve kept fluffing (messing up) his lines. He got quite flustered about it."
