Isla looks so youthful, she was once mistaken for her husband's daughter at a Hollywood party. She says Sacha is the perfect dad to their daughter Olive because he makes her laugh. She explains, "Sacha is wonderful, very attentive, constantly amusing and very hands-on. He's 10 out of 10 I'd say - and then some. He already makes Olive scream with laughter."
