If various internet rumors and celeb magazine reports are to be believed, there could be trouble on the horizon for musician Keith Urban and actress Nicole Kidman. The pair have been reported in various places to be having some troubles, and some even claim that they could be heading for a divorce, although nothing has been confirmed at all by the couple.

A tabloid magazine revealed that Urban did not join his wife at the Cannes Films Festival this year, and that has seeming sparked the core of the rumors that there may be trouble. The report claims that this would have been the time that she'd need him most because her movie, Grace of Monaco, recieved negative reviews.

Since her husband was not there to help her bear the stress of negative ratings, sources came to the conclusion that their marriage must be on shaky grounds. Others though have claimed that the situation more likely simply came about due to conflicting work schedules.

Other reports highlight the fact that Kidman had supposedly canceled one of her appearances in BBC's Graham Norton Show. The actress had stated that she was unwell, but the rumors quickly jumped on the news to claim that she simply wanted to avoid answering questions regarding her marriage.

Other sources say while Keith is more focused on his work, Nicole spends her time with their children. No official statement or confirmation has been released from either party about the divorce rumors.
