Steven Tyler is "really concerned" about his bandmate Joe Perry.
The Aerosmith frontman has admitted he's starting to really worry about the health and well-being of the 65-year-old rocker after he collapsed on stage in Brooklyn over the weekend and allegedly suffered a cardiac arrest, whilst performing with the Hollywood Vampires.
Tyler hasn't been able to get in touch with anyone to find out how Perry is recovering since his health scare.
The 68-year-old musician said: "I don't give a s**t about the band - I want Joe to live. I'm really concerned that I'm not getting any news. I know that nobody's talking to me. I can only tell you that Joe's my brother, and I love him so much."
Tyler is worried that Perry has been overdoing it with his shows with Johnny Depp and Alice Cooper.
He told Billboard magazine: "I know they're putting out nothing, but he's recovering, he's really good, he fainted, exhaustion.
"But I know my brother. He's just about the only other guy that's as passionate about his art as I am.
"He's always asking me to do three, four shows in a row. I can't - I'll blow my voice out. I know hot to maintain my career, my health. I don't think he knows how to."
The 'I Don't to Miss a Thing' hitmaker feels that Perry, Cooper and Depp need to consider the fact they are getting older and aren't as "young" as they used to be and he admitted he thinks they are all "burnt" out.
He added: "I think they're all little burnt. I think they may need to look at that. Not young any more, you know?"
The latest health update on Perry came from Cooper, who said he was in a "stable condition".
He wrote: "Thanks to everyone asking about brother @JoePerry. He is stable right now, with family & is under the best care. (sic)"
The Hollywood Vampires have continued on with their tour without Perry and on their first night they paid tribute to him.
At the end of their set at the Fraze Pavilion in Kettering, Ohio, Cooper lead the crowd to shout "Get well, Joe!".
