Danielle Spencer, the former child star who played sassy tattletale Dee Thomas on the 1970s sitcom “What's Happening!!,” has died. She was 60.

Spencer died Monday after she “lost her battle with cancer,” her brother, jazz trumpeter Jeremy Pelt, announced on Instagram. Spencer had suffered other health issues — including a bleeding hematoma and a spinal cord injury — throughout her life.

“Many of you knew her as ‘Dee,’ but she was more than a child actress,” Pelt captioned the carousel of photos of his sister. “She was a friend, an auntie to my three children who adored her, she was a daughter — and in many ways, my mother’s best friend, she was a veterinarian, she was someone who always remained positive even during her darkest days fighting this disease.”

Pelt added: “She was MY sister and protector.”

In a Facebook statement shared Tuesday afternoon, Spencer’s family remembered the actor-turned-veterinarian for her “compassion and dedication” and “level of courage and grace that inspired all who knew her.” The family thanked fans for their support and requested privacy.
