Nicole Kidman and Antonia Kidman
You must be familiar with actress Nicole Kidman, but did you know the Big Little Lies star has a younger sister? You might not be familiar with Antonia, since she isn’t an actress, but she’s just as successful in her field as her sister. Antonia is a journalist and a TV presenter, and has worked mainly with Australian TV channels.
Antonia has also starred in instructional yoga videos, for which she received praised, and published two parenting books. She is a mother of six, which is part of what got her interested in parenting techniques, and part of the reason why her books were a success. While Nicole moved to the U.S. to pursue her acting career, her younger sister stayed to live in Australia.
