Members of the super group Hollywood Vampires are learning they are mere mortals ...

Aerosmith guitarist Joe Perry collapsed on stage during the Hollywood Vampire's show in New York City on Sunday night -- the musician was quickly transported to a New York hospital where he's currently in "stable" condition.

According to reports, the 65-year-old guitarist was stumbling around during the concert's first song. He then sat down in front of the drum set, then walked off stage and soon collapsed. The band, which includes Alice Cooper and Johnny Depp, played on -- because that's what rock and rollers do.

Cooper addressed Perry's absence to the crowd, explaining, "Joe isn't feeling very well," and then they continued on without him. The band did take a moment to honor their pal -- stopping half way through the concert and walking to the center of the stage and saying in unison, "Feel better Joe."

NBC News confirmed that police transported the musician from the The Amphitheater on the Coney Island Boardwalk by ambulance around 9:40 p.m. His Twitter account posted a status update to his fans, assuring them that he was recovering and doing okay.

The tweet said, "Thanks to all of the fans reaching out and asking about Joe. He is stable right now, with family and is under the best care."

Alice Cooper took to Twitter and wrote, "Thanks to everyone asking about our brother @JoePerry. He is stable right now, with family & is under the best care."

From Johnny Depp's divorce and bar brawls to Joe Perry's health issues, this has been a dramatic summer for the Vamps!
