The announcement was made via a video post on the band's Web site Wednesday. Tyler was sitting with the rest of the band and joked: "I just auditioned and I got the gig."
Aerosmith has been in limbo since Tyler fell off a stage during an August concert, injuring himself and forcing the band to cancel the rest of their summer tour. After that, guitarist Joe Perry said Tyler needed to get his act together. Tyler went to rehab for an addiction to pain killers late last year.
