Nicole Kidman has been enjoying the festive season in Australia, recently returning to Sydney for her first Christmas since splitting from husband Keith Urban.

And the actress marked another milestone on Monday - her daughter Faith Margaret's 15th birthday.  

The veteran actress, 58, continued to show off her naturally curly voluminous red hair in a photograph to celebrate the occasion.

The Babygirl actress beamed as she carried an intricately decorated cake adorned with the words, 'Happy 15th birthday baby!' 

Nicole looked as youthful as ever in the snap, showing off her flawless complexion in minimal make-up and she looked down and smiled at the cake. 

It is unclear where the picture was taken, but it is believed Nicole is still in Australia with her daughters Faith and Sunday Rose, 17, as the trio flew home last week. 

According to People, Nicole was more than happy to be back in Australia for the holiday season.

'This is all she wanted after a tumultuous fall,' a source told the publication.

'She just wanted to celebrate Christmas at home. She's very excited,' they added.

The insider also said that Nicole is feeling 'very blessed' despite the end of her 20-year marriage.

'She's been super positive and focused on things that she's grateful for,' they said.

Earlier this week, the actress was spotted heading to a Christmas party in Sydney with her close friends, Australian journalists Jessica Rowe and Peter Overton. 

She looked effortlessly elegant, her strawberry-blonde hair styled in soft, voluminous waves. 

The following day, she was seen outside St Francis Xavier Catholic Church in Lavender Bay, dressed modestly in a plain, long black dress as she attended Christmas morning mass.

It follows reports that reality may be starting to sink in for Keith following his divorce from Nicole. 

The country star, who parted ways with his Hollywood star wife in September after 19 years of marriage, is allegedly 'wondering if he's made a huge mistake' following their split.

After recently performing private shows for members of Donald Trump's inner circle, the 58-year-old is reportedly feeling more isolated than ever.

'He's got to pay the bills - and divorce lawyers don't come cheap,' a source told Woman's Day magazine of the couple's settlement.

Keith has forked out for the couple's daughter Sunday Rose and Faith Margaret's private school tuition and, according to the publication, needs to make a living in any way he can.

'It's a lonely existence for Keith right now - he's exhausted, isolated and looking at a future he never imagined,' the source added.

'He's also lost his best friend, Nicole, who was also his greatest supporter in life. He's wondering if he's made a huge mistake.'

Keith made headlines in November after he performed at an Australian billionaire's party at Mar-a-Lago.

The private gig, hosted by Anthony Pratt, was attended by Donald Trump, who received $10million from the Visy executive chairman for his election campaign.

Nicole and Keith's breakup shocked fans earlier this year - and the Oscar-winning actress had reportedly been dreading the public's response for months prior.

'She's been stressed because she knew the separation would eventually become public and she was dreading it,' a source told People in early October.

'But she's surprisingly level-headed now that it's out, she's just focused on what's ahead and her girls,' the insider said of the couple's daughters.

The actress and musician's separation was confirmed by Daily Mail on September 29, and Nicole filed for divorce on September 30, citing irreconcilable differences.

Their marriage began to fall apart at the beginning of summer 2025. The split was reportedly a long-term development, stemming from months of quiet separation and diverging paths due to work commitments, according to Daily Mail sources.

Nicole has requested to be the primary residential parent in the custody arrangement.
