Several fans recounted their unpleasant encounters with Weiland during a meet-and-greet session in Boston where the fans paid extra money to meet Weiland and take a photo with him.

One fan posted on the Stone Temple Pilots Below Empty forum that Weiland said "Let's get this s-t done with" when it came time to take a photo with the singer. Other fans posted about similar experiences.

Now Weiland has posted an apology on Facebook for his behavior. He writes, "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. - Scott".
