Nicole Kidman’s younger sister Antonia runs errands in Sydney’s northern suburbs after the death of their beloved mother Janelle

Antonia Kidman looked somber as she walked out in Sydney on Sunday morning following the death of her beloved mother Janelle.

Australian actress Nicole Kidman’s younger sister appeared somber as she visited local shops in the northern suburbs.

The 54-year-old looked casual for the outing in blue jeans, a beige sweater and a black jacket.

Antonia completed her look with a pair of brown boots and carried a shoulder bag as she visited a local bakery.

After purchasing a few items, Antonia was seen walking to her parked car.

The sighting comes after Antonia and her sister Nicole, 57, posted a heartbreaking tribute to their mother on Friday afternoon.

They also shared some never-before-seen photos of the matriarch.

In the post, the Perfect Couple star thanked her millions of fans and supporters for showing their condolences during their time of mourning.

“My sister and I, as well as our family, would like to thank you for all the love and kindness we have felt this week,” Nicole wrote in the joint statement.

“Every message we have received from those who loved and admired our Mother has meant more to us than we can ever express. Thank you from our entire family for respecting our privacy while we care for one another.”

Nicole announced last week at the Venice Film Festival that their beloved mother had passed away at the age of 84.

The Australian actress had to leave the festival and return to her hometown of Sydney to be with her family after the devastating news.

Her mother Janelle died just hours before Nicole received the Best Actress award for her role in Babygirl on the final day of the Venice Film Festival.

“Today I arrived in Venice and shortly after I learned that my beautiful, brave mother Janelle Ann Kidman passed away,” Nicole revealed in a statement read by director Halina Reijn after her win.

“I am in shock and have to go to my family, but this award is for her. She shaped me, guided me and made me.”

“I am beyond grateful to be able to say her name to all of you through Halina, the collision of life and art is heartbreaking, and my heart is broken. We love you all.”

Nicole had a particularly close bond with her beloved mother Janelle and often spoke of her support and influence on her career over the years.

The Hollywood star was born in Honolulu and grew up in Sydney with her mother Janelle and her father Antony, who was a psychologist and died in September 2014.

After living in the United States for a time, the Moulin Rouge star and her younger sister Antonia spent much of their childhood in Sydney.

Nicole pursued her passion for acting as a teenager and was supported by her parents as she rose to worldwide fame.

They both remained closely involved in her career over the years, with Nicole even admitting that she still sought advice from her mother.
