Rumors are once again flying about the state of Nicole Kidman and Keith Urban's marriage, with the latest reports claiming the pair are in the midst of a trial separation after neither one took time off from their busy schedules to work on their allegedly troubled marriage. 

Nicole Kidan & Keith Urban's Marriage Not Suffering?

According to Celebrity Dirty Laundry, the pair's marriage has been plagued by a series of problems, but their hectic work schedules have prevented them from spending time together and working through it. And now, after they initially both agrees to take time off from work this fall to finally do so, Kidman has opted to instead move to London and work on a play called Photograph 51--breaking the agreement and setting the couple up for the path towards divorce.  

"Keith will be on tour for most of the summer, and when he finished that in October, she will still be in London--totally immersed in her theater work," a source said. "They were both supposed to takwe time off in the fall so that they could spend time together as a family. But instead Nicole decided to sign on for a hard-core and time-consuming job. It's a bad sign." 

And with the two both reportedly being sick of their alleged fighting and problems, the decision to move to London couldn't have come at a worse time. 

"They are at the end of their rope with all of the bickering and bitterness. Each of them feels like the other doesn't understand, or isn't willing to fight for their relationship anymore. And friends fear it is just a matter of time before they call it quits for good," the source added.  

The couple have been married since 2006 and have two daughters together--Sunday Rose, 6, and Faith Margaret 4.
