The June 8 episode of The Real Housewives of Beverly Hills took a sombre turn as Lisa Rinna remembered her mom Lois, who passed away late last year while filming Season 12.

"My mom passed in hospice and I'm still in shock, I think," Lisa shared in an emotional interview in the episode, which was filmed at the time of her mother's passing. "She was 93-and-a-half so you know it's coming, but you want to keep your loved one alive if you can.

Lois passed away last November. “Lois DeAndrade Rinna / June 7, 1928 - November 15, 2021 5:05am / Heaven Has a New Angel,” Lisa shared on Instagram at the time.

She posted the tribute alongside a throwback black-and-white photo of Lois. The news was confirmed just days after Lisa shared with fans that her mom had a stroke.

Lois definitely emerged as a fan favorite as RHOBH viewers got to know her over the course of notable appearances on the series. Lois was candid and outgoing, sharing with viewers insights into her life as well as her loving relationship with her famous daughter and family.

"The world loved her and to be able to have shared her with the world is a great gift," Lisa said during the June 8 episode, which featured her traveling to Mexico with the group as she dealt with the loss. "I hold that very close to my heart. She was such a good, good human being. She was just such a light. I'm pretty lucky that I come from that."
