Australian actress Nicole Kidman and husband singer Keith Urban will be on The Oprah Winfrey Show tomorrow. Urban has earlier confirmed that he would be performing in the show's Ultimate Australian Adventure episodes to be filmed later this year.

"Tomorrow, two of the hottest Aussies are here! Nicole Kidman and Keith Urban! The countdown to Oprah's Ultimate Australian Adventure starts now!," says a post on the offical Facebook page for The Oprah Winfrey Show.

Keith Urban was in The Oprah Winfrey Show earlier this November where he confirmed his performance at the much anticipated episodes set to be shot in Sydney this December. Urban promoted his sixth studio album Get Closer to in the United States.

However, the Australia singer did not comment on rumours that his wife Nicole Kidman will also be on Oprah's Australian show. Tomorrow's episode may confirm if Nicole Kidman will indeed be guesting on December 14 and 15 in Sydney Opera House.

Oprah's trip to Australia, dubbed as the Ultimate Australian Adventure, is part of the country's tourism promotion with funding from the federal and NSW government. The visit is in partnership with Qantas and is partly financed by Tourism Australia and the NSW government.

It is reported that Australia would eceive over $100 million worth of international exposure as a result of this venture which is estimated to cost $7.7 million.

It will also be the first Oprah Winfrey episode to be filmed outside the United States. The episode featuring Oprah's eight day trip to Australia will also mark the start of the show's 25th and final season.
