Perry 'aerosmith Future Is Up in the Air'

Aerosmith rocker Joe Perry fears the band will be over once its current tour comes to an end - insisting their future together is completely "up in the air".

Perry recently confirmed his bandmate Steven Tyler has been in talks tojoin the judging panel of American Idol, although an official announcement has yet to be made, and the guitarist criticised the singer for not sharing his plans with his colleagues.

The rocker is now adamant Tyler's new role is a done deal and he's convinced Aerosmith's future is uncertain once their Cocked, Locked, Ready ToRock tour comes to an end in Canada next month (Sep10).

He tells Cincinnati.com, "He (Tyler) told me just a couple of days ago he signed his papers to join the show. As far as he knew, everything's set to go. "I think everybody's a little worn out.

The tour is winding up, and we don't know when we'll work again as band.

That part of it is up in the air, and it's starting to hit home".
