Fans took to social media to rip into the rocker following the gathering backstage at the Brighton Music Hall in Boston, with one devotee revealing Weiland couldn't even bring himself to look at her during a photo opportunity.
She wrote, "I was talking to him, he put his arm around me and literally said 'Lets get this s**t done with'... Scott should not be saying that when people paid 150$ (sic) for a brief picture with him after the show."
Another fan wrote, "He was definitely drunk and ready to get outta there."
Weiland has now taken to his Facebook page to offer his apologies, writing, "I would like to make a sincere apology to the fans that were at the meet and greet in Boston. I'm embarrassed by my behavior and some of the things that I said.
"Fans don't deserve that. Without our fans and supporters, we would not be able to do what we're doing. I put my all into the show that night and honestly was just beyond exhausted... either way, I acted like a total a**hole and for that I'm truly sorry."
