Ozzy Osbourne’s daughter Aimee and her producer escaped a Hollywood recording studio fire that killed another person, her mother said.

The fire erupted on Thursday afternoon in a two-storey commercial building, and it took 78 firefighters more than 50 minutes to extinguish the flames, Los Angeles Fire Department spokesman Erik Scott said.

Two people reported respiratory symptoms related to smoke exposure and were evaluated at the scene but both declined to be taken to a hospital, Mr Scott said.

“Sadly, one person was found dead inside, as firefighters searched the structure,” he said, adding that no firefighters were injured and the cause of the fire is under investigation.

One of the two survivors was the elder daughter of Sharon and Ozzy Osbourne, Sharon Osbourne said in an Instagram post.

Aimee Osbourne, 38, and a producer she was working with were “the lucky two that made it out alive”, Osbourne said, without identifying the producer.

“It is utterly heart-breaking that someone lost their life today in this fire & we are sending our prayers to this person & their family,” she said, adding “our prayers go out to the family and friends of the person that lost their life to this senseless fire”.

Aimee Osbourne is a singer who releases music under the name ARO, her initials. She did not take part in the Osbourne family’s reality show.
