Gibbs, 90, was at the podium giving a speech during the unveiling of her star on the Walk of Fame when she suddenly stopped and appeared to be fainting.
A man wearing a mask who had been in her group of guests hurried forward to prevent “The Jeffersons” star from falling.
Her daughter Angela Gibbs took to the microphone to say that her mother needed a moment “to cool down.” Temperatures rose above 90 Tuesday in Los Angeles.
“I was just overwhelmed for a moment,” Gibbs said. “I have not been thrilled until this moment!”
Famous TV producer and creator Norman Lear, who helped make Gibbs famous, was ready to witness the ceremony.
Gibbs is best known for playing sassy housekeeper Florence Johnson in the beloved sitcom “The Jeffersons,” which ran from 1975 to 1985, and as Mary Jenkins on “227,” which aired from 1985 to 1990.
