Gibbs, 90, was at the podium giving a speech during the unveiling of her star on the Walk of Fame when she suddenly paused and appeared to be about to faint.
A man wearing a mask who had been in her group of guests rushed forward to keep “The Jeffersons” star from falling.
Her daughter Angela Gibbs took to the microphone to say her mother needed a moment “to cool down.” The temperature soared past 90 Tuesday in Los Angeles.
“I just got overwhelmed for a minute,” Gibbs said. “I haven’t been excited until this moment!”
Famed TV producer and creator Norman Lear, who helped make Gibbs famous, was on hand to witness the ceremony.
Gibbs is best known for playing sassy housekeeper Florence Johnson on the beloved sitcom “The Jeffersons,” which ran from 1975 to 1985, and as as Mary Jenkins on “227,” which aired from 1985 to 1990.
