Valerie Bertinelli is looking back at her relationship with her late mother in a touching social media tribute. Taking to Instagram on Friday, July 18, the actress shared a photo of her workspace, and noted the latest decor addition - a photograph of her mother Nancy who died in 2019 at age 82 from rheumatoid arthritis. "I added a picture of my mom just recently," Bertinelli, 65, captioned the post. "This is her at 18, I think. Isn't she beautiful?" As she continued the caption, the One Day at a Time alum reflected on her grief and how much she missed her mother.
