Bella Cruise Kidman has shown her support for her younger sister, Sunday Rose Kidman, after she made her Met Gala debut with their mother, Nicole Kidman.
After fashion’s biggest night of the year, the 17-year-old model took to Instagram to recap the evening, which included sweet moments with her mother on the carpet.
“Florals for spring. groundbreaking,” she wrote on Instagram. “I love my mommy🥰 thank you, Anna, for having me. What a dream!!!! aaand wearing custom @dior – thank u so much jonathan 😭”
Almost 8,000 people liked the sweet post, including Bella, 33.
Nicole adopted Bella after she was born in 1992 and her son, Connor Cruise, in 1995, during her marriage to Tom Cruise, which lasted almost 11 years. They split in 2001, and Nicole married Keith Urban in June 2006.
Sunday was born in 2006, and her younger sister, Faith, was born in 2010.

Bella lives in London with her husband, Max Parker, while Sunday lives in Nashville with Nicole and her sister, Faith.
Though little is known about their relationship, Bella does follow Sunday on Instagram; however, she does not appear to follow her in return.
Bella tends to keep a relatively private life away from the spotlight, but does showcase her art on her Instagram page. Sunday, on the other hand, has established a public career for herself as a model.
Bella’s sweet gesture isn’t the first time that she’s rallied around her younger half-sibling.
She also liked her feature in W Magazine, which Sunday posted to Instagram in March 2025. Not only that, but she also liked a post Sunday made in 2024 about her modelling debut, which no longer appears on her profile.
The model famously walked the catwalk for the first time 12 weeks after she turned 16, per Nicole’s conditions, who kept her children’s lives very private when they were younger.

And the Met Gala was no doubt a huge step for model Sunday, who was allowed to attend alongside co-chair Nicole, even though the Met Gala is strictly an adults-only event.
All eyes were on Nicole and Sunday at the event, because it was another moment of solidarity after her divorce from Keith Urban.
The couple split in 2025 after 19 years of marriage, when the Oscar winner filed for divorce in September 2025, which was finalised in January 2026.
