Queens of the Stone Age frontman Josh Homme has said he is "truly sorry" and is "going to have to figure out some stuff" after he kicked a female photographer's camera and injured her while he was performing in California at the weekend.
Photographer Chelsea Lauren posted a video of the incident to Instagram and wrote: "Thanks to @joshhomme @queensofthestoneage I now get to spend my night in the ER. Seriously, WHO DOES THAT?!?"
Lauren said later she had been released from hospital.
"My neck is sore, my eyebrow bruised and I'm a bit nauseous," she wrote.
Responding on Twitter, Homme initially said he was "lost in performance" and thought he had kicked onstage lighting while his band were headlining the KROQ Almost Acoustic Christmas concert at the Forum in Inglewood on Saturday.
However, an emotional Homme later posted a video, in which he said he didn't have "any excuse or reason to justify what I did".
He began: "Last night at a Queens of the Stone Age performance, I kicked the camera of a photographer, and that camera hit the photographer in the face, and the photographer's name was Chelsea Lauren.
"I'd just like to apologise to Chelsea Lauren. I don't have any excuse or reason to justify what I did. I was a total d***, and I'm truly sorry and I hope you're ok. I've made a lot of mistakes in my life, and last night was definitely one of them. And I apologise for that to you."
"I want to be a good man," Homme continued, "but I think last night I definitely failed at that. And that means I failed my family and my friends as well. I don't want them to ever be ashamed or embarrassed about being around me or knowing me. And so I apologise also to my bandmates and my mom and my dad and my wife and my brother and my kids."
"I'm going to have to figure out some stuff, I think," Homme concluded. "Because rock and roll's a wonderful thing - it's supposed to save and help people, not mess them up. So Chelsea Lauren, I hope you're ok, and I'm truly sorry. I understand you have to do whatever you have to do. I just want you to know that I'm sorry."
