Kelly Osbourne is speaking out after her boyfriend, Slipknot‘s Sid Wilson, suffered burn injuries from a fire accident on their farm.

The daughter of Ozzy Osbourne and Sharon Osbourne issued a stern warning while sharing videos of her partner recovering in a hospital room, with their son Sidney—whose birth was announced in January 2023—playing with toys on the floor nearby.

“This is why you don’t f–k with burn piles,” Kelly, 39, said in a clip shared on her Instagram Stories Aug. 23. “He literally set himself on fire and exploded everything.”

The TV personality later added in another video Aug. 24, “I just want to take a second to say thank you to everyone who’s been sending well wishes to Sid. He’s doing so much better. In fact, we are on the way to go pick him up from the hospital right now.”

Sid, 47, who has since been released home, had documented the experience on his own social media.
