NEW YORK -- Aerosmith's lead guitarist Joe Perry says the legendary rock band isn't breaking up -- although they may be in need a new singer.

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 said Monday on WKXL, a radio station in Concord, New Hampshire, that Tyler hasn't communicated his intentions with anyone in the band and that he found out about Tyler's solo wishes after going online.

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.

"After the tour got canceled, he just kept drifting off and doing other things. We would hear things from different people. He wasn't talking directly to anybody in the band," Perry told WKXL, referring to Tyler. "So basically, he just made the announcement that he was taking some time off."
