Tyler says he's reached out to Perry following the incident but that he hasn't heard any news.
"It's starting to scare me a little bit," Tyler said.
Aerosmith is set to embark on a South American tour on Sept. 29, though Tyler says he's less concerned with the tour and more concerned with Perry's health.
"I don't give a [expletive] about the band. I want Joe to live," Tyler said. "I'm really concerned and worried right now that I'm not getting any news. I'm a little bummed out, and that scares me."
"I can only tell you that Joe's my brother and I love him so much," Tyler added.
Right now the tour is set to go on as scheduled, but first Tyler is working on his own tour for his first-ever solo album We're All Somebody From Somewhere.
The album, which Tyler recorded in Nashville, is his first foray into country music.
"For all the radio and all the folks I've met in country, at the CMT [Awards] and going to radio stations, they're all in love with a good song, and I think I hit on a couple, at least," Tyler said.
