Queens of the Stone Age frontman Josh Homme has apologised for kicking a photographer in the face during a concert, after she shared video of the "obviously very intentional" incident.
The footage shows the rocker walking past photographer Chelsea Lauren then returning to kick her camera, striking her face.
Lauren said she had been excited when she saw Homme approaching her, as she'd never photographed the band before.
"The next thing I know his foot connects with my camera and my camera connects with my face, really hard," she told Variety.
"He looked straight at me, swung his leg back pretty hard and full-blown kicked me in the face.
"He continued performing, I was startled, I kind of stopped looking at him, I just got down and was holding my face because it hurt so badly."
Lauren kept shooting as Thirty Seconds to Mars and Muse performed at the concert, radio station KROQ's annual Christmas event.
She later went to hospital for treatment, and plans to file a police report.
"I feel like if I don't do anything, he gets to kick people in the face and not get in trouble because he's a musician. That's not right," the photographer said.
'I did not mean for that to happen'
In a statement, Homme said he would "never intentionally cause harm to anyone working at or attending one of our shows" and issued a "sincere apology" to Lauren.
"Last night, while in a state of being lost in performance, I kicked over various lighting and equipment on our stage," he said.
"Today it was brought to my attention that this included a camera held by photographer Chelsea Lauren. I did not mean for that to happen and I am very sorry."
Lauren said no-one from the band had reached out to her directly, but she thanked members of the public for "supportive messages".
"My neck is a sore, my eyebrow bruised and I'm a bit nauseous. The doctor released me early in the morning," she wrote in an Instagram post.
'He just stared at me smiling'
She said after he kicked her, Homme took out what appeared to be a knife and deliberately cut his own forehead.
Blood dripped down Homme's face for the rest of the performance.
"Here are three images. Two of them as Josh looked at me, smiled and then kicked me. The other one is later after he cut his own face with a knife," she wrote.
"I was in the pit in tears — and he just stared at me smiling.
"Assault in any form is not OK, no matter what the reasoning.
"I was where I was allowed to be, I was not breaking any rules.
"I was simply trying to do my job."
