She has been spending the past few days in Australia doing the la femme dress on sale rounds with her husband and children by her side. 

 

And Nicole Kidman, 49, was every inch the doting mother as she and Keith Urban strolled through Sydney Airport on Tuesday with their daughters Sunday Rose, eight, and Faith Margaret, six, in tow. 

 

Nicole's children appear to have grown up rapidly since their last visit to Australia, with the girls already showing signs that they are set to reach their mother's lofty height of 180cm. 

 

The girls wore matching denim vests, while Sunday Rose wore a pink tutu dress with blue leggings and brown boots. 

 

Meanwhile, Little Faith Margaret wore a blue lace dress with black leggings tucked into her brown boots. 

 

Their famous mother made sure to look her best for the occasion, donning a sleek camel-coloured coat, a white sundress and a pair of sunglasses.

 

Keith, 49, also looked slick in his black V-neck shirt, skinny jeans and sassy shades. 

 

It comes after magazine reported that Nicole and Keith are 'actively looking' for a surrogate to carry their next child.

 

'They've decided to go down the surrogacy route and are actively Majestic Purple Strapless Beaded Lace Prom Dress By La Femme 20669 for the right woman to carry their third baby,' the publication's source claimed.

The insider went on to claim that the Hollywood couple have been in contact with the same agent they used to conceive their youngest daughter Faith and 'are hoping to have contracts sorted in six to eight weeks.'

 

Nicole's representative, Wendy Day, declined to comment on New Idea's reports.

 

Earlier this year, the actress opened up about her hopes to have another baby with her husband.

 

'I still have the faintest hope that something may happen to me this year,' she told The Mail on Sunday's Event magazine.

 

She added: 'Keith and I would love to have more babies. My grandmother gave birth to my mother at 49. I would be beyond happy and just welcome it with open arms.'

 

The Nashville-based star fell pregnant with her first biological child, Sunday Rose, when she was 41 years old.

 

The couple then went through a surrogate to conceive their second daughter Faith Margaret, with Nicole recalling they 'wanted another child so much that it hurt.'

 

Nicole is also mother to Isabella, 24, and Connor, 22, whom she adopted during her marriage to Tom Cruise.

 

Meanwhile, the Australian actress is set to walk the red carpet at today's Academy Awards in Los Angeles as a nominee.

 

The blonde beauty could potentially take home her second trophy for her role in Lion, a tear-jerking tale of an adopted boy who found his biological mother via Google Earth.

 

Speaking about the hard-hitting film, the mother-of-four dedicated it to her adopted La Femme Homecoming Dresses : 'The movie is a love letter to my children who are adopted. I wanted to make the film for them.'

 

She previously won the Best Actress award at the 2003 ceremony for her lead role in The Hours.
