“She just started saying ‘uh-oh’ and it’s the funniest thing,” Cuoco, 38, revealed on the Monday, January 15, episode of The Jennifer Hudson Show. “I’m convinced that she says it at the correct time like something will drop and she’ll hear something on TV and go, ‘Uh-oh.’”

Cuoco went on to call her 9-month-old a “genius” for using “uh-oh” because “she knows what it means.” Matilda’s intelligence is something the Flight Attendant star joked her daughter inherited from her, telling host Jennifer Hudson, “Yes, the genius, of course!”

Another of Matilda’s favorite things is music, so Cuoco put her musical tastes to the test one day by playing her daughter the Big Bang Theory theme song. “I turned it on one day and she sat there and loved it,” Cuoco, who starred on all 12 seasons of the CBS sitcom, shared.
