The 68-year-old presenter shared the news on Monday in a post on her verified Instagram account.
Osbourne wrote that she had been briefly hospitalized with the contagious disease.
“I wanted to share that I tested positive for COVID-19,” his post on Instagram said. “After a brief hospitalization, I’m now recovering in a place away from Ozzy (which has been negative) while The Talk has a scheduled hiatus. Everyone, please stay healthy and healthy.”
Her revelation comes days after the news that her roommate “The Talk,” Carrie Ann Inaba, shared that she tested positive.
In September, Osbourne quarantined her and appeared on her show via a video link after saying one of her young granddaughters had tested positive.
Osbourne is a colon cancer survivor and her husband, rocker Ozzy Osbourne, has Parkinson’s disease.
In March, her daughter Kelly Osbourne expressed concern over her health amid the pandemic.
“I wish there was something I could say to comfort you all. A little wisdom could let you down to relive the fear that surrounds us right now,” he wrote on Instagram. “The truth is, I’m scared too. My parents are at high risk, especially my father.”
