Henderson famously played matriarch Carol Brady for the five immensely popular seasons of The Brady Bunch (1969-1974), while McCormick played her eldest daughter, Marcia. McCormick recalled being 12 years old when she met Henderson, who left an indelible first impression.
"I was just like, 'Wow! She's so beautiful,'" McCormick fondly remembered. "That woman in no makeup was the most beautiful thing."
Away from The Brady Bunch set, McCormick spent "pretty much every weekend" at Henderson's house with her family. McCormick said they would "hang out in our pajamas all day" or "be in our bathing suits by the pool."
Despite their 22-year age difference, the two formed a strong bond that lasted up until Henderson's death.
"Florence played our mother on the show, but I always felt like she was more of a sister,” McCormick, 60, shared. “She was so young at heart, and just a really good friend."
