Today, Oprah Winfrey premiered her 'Oprah's Ultimate Australian Adventure' episode, which featured Keith Urban and Nicole Kidman's first sit-down interview together. The show was filmed at Sydney's Opera House back in Dec. 2010, and featured everything Australia, from Aussie celebrities like Urban to sightseeing throughout the country.

Oprah Winfrey welcomed Urban and Kidman onstage to a rousing round of applause from the thousands of fans watching. Urban was looking sleek in all black, while Kidman looked graceful and elegant in a flowing white dress.

During the interview, it was obvious how in love the couple is, with Urban keeping his arm around Kidman the entire time. The happy couple and both appeared on 'Oprah' not too long ago, but they were interviewed separately. As they sat down together for their first joint interview, Kidman said, "We saved it for Australia."

Oprah then got the interview underway by asking what the biggest difference was that they saw between Aussies and Americans. Kidman went on to elaborate while Urban jokingly replied, "The accent." Urban continued to joke as Oprah asked what they liked to do when they visited their homeland. Kidman answered, "We swim in the ocean," while Urban said, "Chat with you."

Although Urban let his beautiful wife do most of the talking, he did share with Oprah what he misses most about Australia. "We love the ocean," Urban said. "That’s the one thing I miss about Nashville, is the ocean." The couple also shared that they have a large property in Australia where they raise cattle, alpacas and chickens.

The show finished off with a performance of Peter Allen's 'I Still Call Australia My Home' by the Australian Children's Choir. Urban came out to sing a few lines, followed by Kidman. It was obvious that Kidman looked a little shy about singing in front of a large crowd, however, her hubby encouraged her by saying, "Take it away girl!" Australian actors Hugh Jackman, Olivia Newton John and Russell Crowe also joined in the patriotic singalong as a giant Australian flag was unfolded over the audience.

This week, Urban and Kidman welcomed the newest addition to their family, baby girl Faith Margaret, who was born via surrogate. The couple also have a 2-year-old daughter, Sunday Rose.
