The Nicole Kidman and Keith Urban divorce rumors are again fueled by the box-office failure of "Grace of Monaco," as Tom Cruise's ex is supposedly dodging questions about the status of her marriage.

According to the Daily Star tabloid, Nicole Kidman and Keith Urban divorce might be happening soon when the "American Idol" judge wasn't around during the recent Cannes Film Festival where "Grace of Monaco" was shown.

Then Nicole Kidman ditched her scheduled appearance at the "Graham Norton Show" over at BBC, claiming that she was not feeling well.

"It's clear she didn't want to face questions about her marriage," the source told Daily Star. "It seems she and Keith really are on shaky ground. Keith didn't appear to want to free up one day in his schedule to be with her in Cannes when she needed his support the most."

However, the Nicole Kidman and Keith Urban divorce rumors seemed to be quashed by the couple with their many appearances together recently. Last week, in fact, the "American Idol" judge dedicated the song "Once in a Lifetime" to his wife during a performance in Allphones Arena in Sydney.

"I wrote this song for my wife and she's here tonight ... she is an extraordinarily pure and beautiful light. I love you baby," he said, according to New Zealand Herald.

The couple has two daughters--Sunday, 5, and Faith, 3-and Nicole Kidman also has two older kids she adopted with ex Tom Cruise.

The Nicole Kidman and Keith Urban divorce rumors have been hounding the couple these past few months and the country singer indirectly addressed them in a recent interview with Rolling Stone.

In the interview, the country singer described Nicole Kidman as "from another planet."

"She is so celestial. I say that I was born into her. That is the best way I can describe how I feel about her and us. It means that I felt like I was just sitting dormant, and she came along and I came to life," he said.
