Australia’s very own nepo babies Sunday Rose Urban and Sam Rechner have gone public with their very sweet friendship on social media. 

The daughter of Hollywood heavyweight Nicole Kidman and the nephew of Nine’s Peter Overton are the closest of pals, enjoying holidays together and even having adorable nicknames for each other.

Sam, 23, posted a slew of cute photos of Sunday to Instagram on Wednesday to celebrate her 17th birthday, while also revealing his pet name for the famous youngster.

‘Happy Birthday ciao ciao mui mui,’ he captioned the post, which showed the pair throwing peace signs in a film photo. 

Another picture taken by Sam showed Sunday looking radiant in a rose-covered frock as she stared down the camera.

While it is not known how long the two have been mates, they seem to be family friends, with Sunday’s mum Nicole Kidman and Sam’s uncle Peter Overton living next door to each other while growing up.

What’s more, Peter’s sister aka Sam’s mum Annette was said to be best friends with Nicole when they all attended Lane Cove Public School in Longueville together.

The families are so close that Nicole asked Sam to accompany her on the Oscars red carpet in 2023, along with her husband Keith Urban.

Sam is best known for his work on the screen, playing the role of Logan Hall in The Fabelmans, directed by Steven Spielberg.

Sunday on the other hand has become a regular in the modelling world, appearing in campaigns for major brands such as Omega and Miu Miu – perhaps the origins of Sam’s nickname for her. 

Despite scoring many modelling gigs lately, Sunday was initially roasted online last year over her runway debut at Paris Fashion Week.

In October, she opened the Miu Miu Paris Womenswear Spring-Summer 2025 show, which was attended by the likes of Willem Dafoe and Hillary Swank.

Sunday strutted in a white sleeveless dress – the same one from the campaign image – paired with grey leg-warmers and black peep-toe heels.

While her mum Nicole showed her support both at the show and following her runway debut, many critics on the internet hit out at Sunday Rose’s walk.

Some people suggested she take runway lessons, while others simply complained that too many nepo babies think they can model.

Sunday Rose’s serious stomp quickly went viral on TikTok, with commenters calling her out and suggesting she find another career path.

‘Try painting or acting instead. This is not for her,’ one suggested, as another commenter agreed, ‘Oh please why be a model so many other things to do.’

‘I can hear the heels slapping the floor,’ another person critiqued.
