"The Real Housewives of Beverly Hills" has "paused" production, a source told Fox News.
The news comes after stars Lisa Rinna, Erika Jayne and Garcelle Beauvais reportedly tested positive for coronavirus.
Beauvais, 55, shared the news of her diagnosis on Instagram on Monday but did not make mention of her co-stars or the status of the reality show's production.
"I found out that I tested positive for COVID," she shared in a brief video. "I feel OK. I'm sure I will continue to feel OK."
