Kelly Osbourne has claimed one of her father Ozzy's friends introduced her to cocaine.
The TV personality made the shocking allegation in a new documentary about LA's Sunset Marquis hotel.
Sharing stories about the West Hollywood institution, Kelly confided she had been offered the illicit drug at that venue by a member of a "very big band".
"I did my first line of cocaine in this hotel," the 41-year-old said, in If These Walls Could Rock. "Which was given to me by one of my dad's friends in a very, very, very big band."
She added she had kept the indiscretion under wraps for years, as she knew her father, who was the frontman for heavy metal band Black Sabbath until his death in July 2025 at the age of 76, would not react well.
"I could never tell my parents because they would f**king kill him!" Kelly quipped.
The actress and reality star explained she had grown up staying at the storied hotel, famous for its association with rock and roll, as it was "the only hotel that my dad could stay in, at the time, where my dad could be himself."
"We'd be kicked out of everywhere, but not the Sunset Marquis," she said, adding: "My dad could misbehave politely here."
Furthermore, Kelly's mother, Sharon Osbourne, said Ozzy treated the property as if it were his own home.
"He would love it here because he could wander. He could wander around outside in the garden. In those days he'd smoke," Sharon, 73, recalled.
"It was like you were in your own home with a lot of friends."
