That’s what siblings are for! Nicole Kidman had nothing but kind words to say about her younger sister, Antonia, who just graduated from law school.

“Congratulations to my darling sister who graduated with her law degree,” the 51-year-old captioned Instagram photos showing Antonia, 48, in a graduation gown with and one of her sis and their mother, Janelle. “Studying, raising six kids and starting a new phase in her career, and she’s doing it all with grace and humility.”

“I just wanted to acknowledge her because so much of what makes me, me, is my family. I also want to acknowledge our mum, who from when we were little, believed in us, educated us, guided us and continues to do so. I love both of these women so much,” the Oscar winner added. Take a look at the post below!

Antonia was once asked if she is comfortable living outside Nicole’s spotlight now that she’s older. “I think so, and maybe living in Singapore, too,” she told the No Filter podcast at the time.

She may not be in various Hollywood movies like her big sister, but Antonia does star in two yoga instructional videos, and she’s even written two books on parenting. When she isn’t busy with her career, the Australian journalist has her hands full with her family.

The former newscaster welcomed her four eldest children — Lucia, 21, Hamish, 18, James, 16, and Sybella, 12 — with her first husband, Angus Hawley. The pair married in 1996 and divorced in 2006. Tragically, Angus passed away after suffering a heart attack at the age of 46 in April 2015.

In 2010, the author tied the knot again with Craig Marran, 51. The couple, who are still together, share two other children — Nicholas, 8, and Alexander, 6.

We are just so happy to see Nicole supporting her sister through all of her accomplishments in life!
