Perry said on the micro-blogging site Twitter late Monday that Aerosmith is "not splitting up" but "looking for a new singer to work with" amid growing speculation about the future of the band and the role of front man Steven Tyler.
Tyler has been quoted as saying he is considering a solo career.
Perry tweeted that one of the band's members "is doing his own thing and said so in the press. That's all I know."
Tyler could not immediately be reached for comment.
The 61-year-old Tyler was injured when he fell off a stage during an Aug. 5 performance in South Dakota, and the band canceled the remainder of its summer tour.
