Slipknot’s Sid Wilson has been admitted to hospital for “serious burns” across his body after he got caught in a bonfire “explosion” on his farm.

The American musician, who is in a relationship with British singer Kelly Osbourne, announced the news by posting a video from his hospital bed, but said he was going to be “OK”.

Despite his injuries, the heavy metal band said in a statement that Wilson still planned to join the group for their performance at Rocklahoma festival in Oklahoma next weekend.

In the Instagram video, Wilson was lying in a hospital bed as medical staff treated the wounds on his face and arms.

He told the camera: “Hi everybody, I had an explosion in my face. I’m OK, I’m going to be OK. But I did have some serious burns to my face and my arms.”

The DJ said he was getting his chest X-rayed to ensure he had not inhaled flames from the fire, and showed off his singed eyebrows and moustache, his blistered mouth and arms.

“I’m going to be all right you guys. I don’t care what it takes, I will see you on tour,” he added.

He posted a follow-up video while being transferred to a more specialist facility, in which he assured fans he was doing “pretty good” and that he was in “good hands”.

He also explained that he sustained the injuries from the remnants of a bonfire which he had burned on his farm the night before.

Osbourne, the daughter of TV star Sharon and Black Sabbath vocalist Ozzy Osbourne, also warned others about the dangers of burn piles in a video from his hospital beside.

She says: “This is why you don’t f*** with burn piles. He literally set himself on fire, exploded everything.”

She also shared a video of their young son playing with toys on the hospital floor beside Wilson, who was wrapped in bandages.

Slipknot later posted a statement on Instagram about Wilson’s accident, saying: “Our brother Sid Wilson was in an accident today and sustained burns across his body.

“He’s recovering with his family and will still join us on stage at Rocklahoma next weekend.

“He thanks everyone for the well wishes, and will see you all soon.”

The heavy metal band will embark on a global tour from September, playing dates in the US and South America before travelling to Europe.

The group will kick off the UK leg of their tour in December in Leeds, with shows scheduled for Glasgow, Manchester, Birmingham and London.
