Nicole Kidman heads to church alone for a Sunday morning service in Sydney as husband Keith Urban jets out of Australia

Nicole Kidman and her husband Keith Urban enjoyed a Christmas party Down Under.

But on Sunday, Keith was spotted at Sydney Airport while Nicole attended a local church service.

The actress dropped by for Sunday service at the North Sydney Chapel and appeared to be going solo, her children were also not seen in tow.

The Moulin Rogue actress opted for a chic all-black ensemble including a dress with puffed sleeves.

She added a pair of satin Mary Jane flats and wore a ribbon in her strawberry blonde curls in the same fabric.

Nicole completed her look with designer sunglasses and a leather crossbody bag, while she opted for a natural makeup palette.

Keith, meanwhile, kept it casual as he crossed the terminal at Kingsford Smith Airport with a backpack slung over one shoulder.

The singer wore a fitted black shirt with graphic print, jeans and white sneakers.

The country crooner completed his look with sunglasses and a simple navy cap.

He beamed as he made his way to his gate for his flight and appeared to be leaving the country.

The couple previously kicked off their Christmas celebrations with a visit to a church service in Sydney.

The Hollywood actress and musician, both 57, returned Down Under for the holidays with their two daughters Sunday Rose, 16, and Faith Margaret, 14.

The family, who live in Nashville, kept to their Christmas traditions as they started the day by attending a church service at St Francis Xavier Church in Lavender Bay.

The chapel is Kidman’s local church and holds a special place for them as it was where the funerals of Nicole’s mother Janelle and father Antony were held.

Stepping out for the Christmas Day service, Nicole looked elegant in a black dress with a ruffled neckline, which she styled with dark sandals.

Nicole’s two adopted children, Isabella, 31, and Connor, 29, who she shares with her ex Tom Cruise, are said not to have joined them on the trip Down Under.

Nicole has flown back to Australia to reunite with her younger sister Antonia, 54, and her family as they spend their first Christmas without her mother Janelle.

The family has rallied to support each other during the bittersweet time as they all spend time together during the holidays.

The chapel where Nicole and her family attended the Christmas Day service holds a special place for the family as they have been regulars there for years.

They also said goodbye to Nicole’s mother Janelle there in September, as the family all gathered for the funeral service.

Ten years earlier, the funeral of Nicole’s father Antony also took place on September 19, 2014 in the St. Francis Xavier Church.

It’s not the first time the Kidmans have visited the church since Janelle’s funeral, as Nicole joined Keith and her daughters there on Monday, just days before Christmas.

Janelle sadly passed away at the age of 84 in September – just hours before Nicole won the Best Actress award for Babygirl at the Venice Film Festival.

It is tradition for Nicole to fly back to Australia over the Christmas period and she and Keith often host New Year’s Eve celebrations at their Sydney Harbor apartments.

Over the past decade, Nicole has purchased two penthouses in the exclusive North Sydney Latitude building and then combined them into a mega apartment.

When Nicole is back in Sydney this Christmas, Nicole will no doubt reunite with her sister Antonia and her family.

The Kidman clan has already had a festive catch-up in recent weeks after Antonia visited Nicole in Nashville earlier this month.

Antonia was joined by her daughters Lucia, 26, and Sybella, 17, for the trip as they crossed over to stay at Nicole’s $4.9 million Nashville mansion.

Lucia, who lives in Sydney, shared festive snaps from the holiday on her Instagram at the time as she documented the trip.

She was accompanied by her boyfriend Henry Poole, while Antonia’s husband Craig Marran also flew with them.

Nicole’s sister Antonia shares her two daughters and two sons Hamish, 23, and James, 21, with the late businessman Angus Hawley, who died in 2015.

She also has two younger sons Nicholas, ten, and Alexander, eight, with her second husband Craig.
