Up until now, Keith had managed to stay out of the limelight, but Aussie newspapers recently spotted him with his parents and soon-to-be step-kids, ISABELLA and CONNOR, as they soaked up the sun on NICOLE KIDMAN’s 4.5 million dollar yacht. Nicole’s adopted children with former husband TOM CRUISE are reportedly quite taken with the country singer.

Keith’s brother and best man, SHANE, was also along for the cruise around Sydney harbor as they relaxed before the wedding.

New reports have also revealed that a $100,000 wall of roses will be among the impending celebration’s highlights.

Meanwhile, is Nicole having a style crisis? The big rumor surrounding her upcoming nuptials to KEITH URBAN involves her wedding dress, and ET has the latest!

Nicole’s gown, reportedly furnished by BALENCIAGA, may undergo some last-minute alterations before the big day. Australian designers are said to be pitching in at the last minute to complete the final touches.

We’ve heard it’s going to be a strapless yet conservative design in white. Considering how she often opts to wear dresses with a sleek line that create a silhouette of her fabulous figure, this would be a “perfect fit” for the Oscar®-winning star.

We’ve also learned that while reports earlier in the week indicated that the newlyweds would be heading to Fiji for their honeymoon, now the couple are said to be jetting off to the island of Bora Bora after the ceremony.

With global interest mounting in the event and the media tracking her every move, Nicole appears to have had enough of the constant attention. With her two children in tow, she was swarmed by reporters yesterday and could hardly make it through the crowd.

“Maybe give me a break guys,” she requested as they tried to squeeze their way through the throng of paparazzi.

Due to heightened security concerns, Nicole and Keith have hired a private security team, and local police have been asked to help keep the peace while the big event takes place. Even the chapel and reception area are surrounded by a high, sandstone wall that will help to ensure privacy.

And the latest celebrity spotting in Sydney is HUGH JACKMAN, one of several fellow Aussie stars to join Nicole and Keith for their big day.

Hugh and his wife, DEBORRA-LEE, flew in from Shanghai, according to the Sydney Daily Telegraph. When asked about the upcoming nuptials, the ‘X-Men’ star played it cool with reporters, saying “Wedding? What wedding?” Source
