It’s Catherine’s 10-year-old niece Ava Zeta.

Zeta-Jones has an older brother, David, and a younger brother, Lyndon; it is not known which relative Ava is linked to. 

The movie icon and the child were seen holding hands on July 30 at Central Hall, Westminster in London, England.

Catherine looked every inch a Hollywood glamour queen in a Stephane Rolland dress with Yeprem jewelry. 

The Traffic star has a close bond with her young niece and has shared photos and videos of her on Instagram over the years. 

In 2021, she posted a cute video of Ava talking in Welsh; Catherine grew up in Wales.

‘Welsh in Spain. Ava Zeta is in the house. Hours of fun. Love you Ava,’ she captioned the clip.

Ava even referred to Catherine as her Auntie Catherine in a video where she delivered a mock acceptance speech with Catherine’s Oscar trophy.

The Instagram post features Ava holding on to the Best Supporting Actress statuette, which Zeta-Jones won in 2003 for Chicago, as she thanked the people closest to her. 

‘Thank you so much! I would like to thank my mommy, my daddy, my nanny and my Auntie Catherine,’ Ava said.

‘My niece Ava Zeta with the perfect acceptance speech. So well deserved!’ Zeta-Jones wrote next to the video.

Zeta-Jones wed Douglas at the Plaza Hotel in New York City in 2000. They have two children: son Dylan Michael, born in August 2000, and daughter Carys Zeta, born in April 2003.

Catherine shared a snap where she and Douglas were kissing Carys on both cheeks as she marked the end of her studies at Brown University in Rhode Island.

The proud mom went on to share several Instagram stories including footage of their daughter in her graduation robes. 

Catherine and Carys also held hands for a sweet moment where they kissed each other again on the cheek. 

The occasion, which saw Carys obtain a degree in Film and International Relations from the prestigious Ivy League school, was also celebrated with a carrot cake.
