Eighty-two year-old Oscar-winning actress Cloris Leachman has been hospitalized after falling ill with pneumonia last Thursday in Los Angeles .

Cloris, who made waves with her potty-mouthed humor on ABC’s Dancing With The Stars earlier this season, was headed home with her son George when she told him she was having trouble breathing and needed to be taken to the hospital.

She was treated in a Los Angeles-area medical center, ET sources confirm.
