Dr. Spencer played the wisecracking Dee Thomas on the 1970s sitcom “What’s Happening!!” and became a veterinarian later in life.

Child star Danielle Spencer, who portrayed Dee Thomas on the 1970s comedy TV series “What’s Happening!!,” has died at 60, according to former co-star and friend Haywood Nelson.

Pelt’s interview with TMZ revealed that Spencer was “talking and alert” while family was visiting her in the hospital this past weekend. Spencer experienced a “code blue,” according to her mom, and was transferred to the ICU. Pelt said that Spencer died of cardiac arrest and gastric cancer.
