*Florence Henderson, the former Broadway star who became one of America’s most beloved television moms in “The Brady Bunch,” has died of heart failure, her manager Kayla Pressman said in a statement. She was 82.

Henderson died at Cedars-Sinai Medical Center in Los Angeles on Thursday night, one day after she was hospitalized, and three days after attending “Dancing with the Stars” to support her former on-screen daughter Maureen McCormick as she competed for the Mirror Ball trophy.

“Dancing With the Stars” host Tom Bergeron tweeted, “Heartbroken. I’ll miss you, my friend.”

Henderson, who competed on “DWTS” during season 11, also surprised McCormick in September at the season 23 premiere.
