Lisa Rinna announced the news of her father Frank's passing with a heartfelt tribute posted on Instagram Thursday. "The World lost a Great Man today," Lisa wrote in the caption to a photo of her father and her mother Lois. "Heaven got a great Angel. I love you Dad."
We saw Lisa cope with her parents' aging and health issues last season on The Real Housewives of Beverly Hills when the actress returned to her hometown of Medford, Oregon to visit them in a senior home and say goodbye to the house she grew up in before the family sold it.
Last April, Lisa revealed on Twitter that her father was admitted to the hospital after coming down with pneumonia for the fourth time that year.
Lisa shared other memories of Frank on Instagram Thursday, such as this photo of the pair on her wedding day in 1997.
She also showcased one of her dad's beautiful paintings.
Lisa thanked her fans for their support during this difficult time on Twitter Thursday. "Thank you for all of your kind messages. My family and I so appreciate all of the love," she wrote. "Dad passed singing 'My Way' Sinatra was his fav."
