The Aussie Power Couple ™ Nicole Kidman and Keith Urban have been spotted and photographed together, again.

Despite the denials that they are engaged, the two are definitely an item as the paparazzi catch them in city after city.

Just Jared is on the case:

This past week Nicole Kidman, 38, her sister Antonia Kidman, 35, and Antonia’s husband, Angus Hawley, flew in to watch country music star Keith Urban, 38, in concert. Afterwards, all four flew together to Las Vegas for The 2005 Radio Music Awards where Keith Urban performed his smash his “Better Life”.

Keith Urban took away the Artist of the Year Award (Country Radio) and accepted his award saying, “Thank you very much. Thank you to country radio for playing my records. And, I want to thank everybody else in this category with me. Everybody in there has been a great help to me. Thanks and Merry Christmas!”

Just last week, Nicole Kidman’s representative denied that she is pregnant (another rumor about the couple that is white hot) and engaged to the hunky country singer.

But gossip site TMZ.Com staffers spotted the striking actress with an engagement ring on her wedding finger in Las Vegas, according to a report on that web site.

Engaged or not? Pregnant or not? Denials are everywhere.
