Diaz visited The Tonight Show Wednesday and talked about her love of pulling jokes – even on newborns.
Diaz told host Jimmy Fallon about how she wants to prank Drew Barrymore's newborn daughter, Frankie. Fallon, for his part, recalled the time Diaz pranked his child – when she was just 6 weeks old.
"She fell asleep first. That's what happens when you fall asleep at a party," Diaz said. "She's a baby!" Fallon responded in mock anger.
As it turns out, Diaz pulled the old "hand in a cup of warm water" trick on little Winnie.
As we said, no one is safe.
