They trashed the place," the eyewitness tells Planet Gossip's Matt Donnelly. "Furniture was knocked over, and they wrote the word f–k on the bathroom mirror in shaving cream."
The eyewitness reports that they also left behind several urine-soaked bath towels.
And this may not have been their first-time offense. When one of the Fall Out Boy roadies was told about the mess from a Pavilion staffer, he said he wasn't surprised.
"Last week," the roadie told the staffer, according to our eyewitness, "they knocked down a wall, so they could crawl between two dressing rooms. This happens in every city."
I hope the venues are charging them and not the record companies for the damage to their dressing rooms because that is not cool.
