Kelly Osbourne is opening up about her battles with drug and alcohol addiction, stopping by "Red Table Talk" to discuss getting hooked as a teen and relapsing after the pandemic.

The TV personality said she ended almost four years of sobriety in April 2021 as the COVID-19 pandemic was waning, triggered into drinking alcohol again after seeing a couple sipping champagne.

"I was alone, sitting by a pool and waiting for somebody to come have a meeting with me. And I saw this woman and her husband had a glass of champagne. It looked really nice and I was like, ‘I can do that, too,’" she said on the Facebook Watch show. "And the next day, I had two glasses. And the day after that, it was bottles."

Her first opiate-based drug addiction was with Vicodin which was prescribed to her after an operation to remove her tonsils when she was 13, sending her on a lifelong battle. "That was all I needed," she said sadly.

Osbourne said the drug silenced her insecurities. "It felt like life gave me a hug." Pinkett Smith responded wryly: "Vicodin will do that." Osbourne added that Vicodin led to her misusing Percocet to eventually heroin "because it was cheaper."

Osbourne has discussed her drug and alcohol battles before in several interviews, her 2017 memoir and on podcasts like Dax Shepard's "Armchair Expert."

She has said her drug use became the heaviest during her mother’s cancer battle and after her father, "Crazy Train" singer Ozzy Osbourne, almost died after an ATV accident in 2003.
