They have denied reports their marriage was in trouble in their marriage and even put on some loved up displays in recetn public appearances, but a new report indicates that things are more critical than ever in Nicole Kidman and Keith Urban's 10-year marriage, and the pair is enrolled in a last-ditch effort to save the relationship.

The two, who have been rumored to be having problems, have allegedly enrolled in a $8,000 private couple's retreat, which lasts two days and will force the couple to discuss their emotions and talk through their problems and differences. However, if it doesn't work, a source alleges that it will mean the pair will soon announce their intention to divorce.

"Nicole and Keith have been battling problems for a long time now and it's gotten to the point where it's make or break," a source told Women's Day Australia (via The Sun). "Nicole has told friends they're giving their marriage three months and have decided to go their separate ways and consciously uncouple if they can't work through their problems."

The report comes after the pair have been plagued by rumors in recent months, and after they have also seemed to try and work hard to prove everything being written about them is false. After initial reports claimed they hadn't seen each other in months and Kidman was "walking a tightrope" when it came to the marriage, the two gushed over each other on social media for Urban's birthday, and also made appearances together that saw them looking happier than ever at the Instyle Awards, the CMAs, the premiere of Kidman's movie Lion, and a joint appearance on The Tonight Show with Jimmy Fallon.

Urban himself even spoke out against all the rumors, saying that people often made stuff up about him and his wife because they largely lived their private lives with their daughters, Sunday and Faith, out of the spotlight, with their usual home base being in Nashville and away from the glare that comes with living in L.A.

"People make up the most insane crap and we kind of just roll with it," he said. "I want to live our life together and the fact we live somewhere where we're not being photographed all the time-it makes it possible for people to make up that stuff because you're not always there to defend it."
