Kelly Osbourne has never shied away about discussing her struggles with addiction, and in a new interview spoke about how her first stint in rehab at age 19 "was like university on how to be a better drug addict.”

“I’d learned so many tricks, so many things that I never even thought of from my fellow addicts that were in there," Ozzy Osbourne's daughter confessed, adding, “I’d also seen people threaten to leave until they got given what they wanted, whether it be Ambien for sleep or Valium for nerves — they’d end up getting it.”

She went on to describe "body brokers" who preyed on vulnerable people. “They’ll sit outside of AA meetings looking for weak and vulnerable people that they encourage to relapse so they can then pick you up again," Osbourne said. “I swear on everything that it is true, and it is heartbreaking.”

Osbourne, who welcomed her first child in late 2022, has previously said she first became addicted to drugs at age 13, when she was prescribed Vicodin after tonsillitis surgery.

“Very quickly, it went from Vicodin to Percocet, from Percocet to … to heroin, eventually, because it was cheaper,” she said during a 2021 interview. “I got caught buying it, and then the very next day, my mom put me in rehab.”

She spent years in and out of rehab and in 2017 quit drinking; however, in 2021 confessed that she relapsed after four years of sobriety. The relapse was short-lived and Kelly quickly got "back on track."

"This is something I am going to battle for the rest of my life," she said at the time. "It’s never going to be easy."
