They've always maintained that their relationship and 10-year marriage is strong and they are more in love than ever, but a new report claims that Nicole Kidman and Keith Urban could be headed for a divorce.

According to In Touch Weekly (via Hollywood Life) the pair are on the verge of a split because Urban has "reached his breaking point" over Kidman's "controlling actions."

"He feels like he's living in a dictatorship rather than a marriage," a source said.   

According to the source, Kidman keeps a very close eye on her husband, who struggled with addiction issues when they first got together, but has been clean and sober for years. However, she has reportedly gotten more intense lately when she checks up on him, and it is driving their marriage apart.

"Nicole's always kept a close watch on Keith because of his wild past and troubles with addiction, but it's becoming so intense lately that it's tearing their marriage apart," the source said. "Nicole's started to keep track of Keith's phone and makes him report to her with his whereabouts and who he's with."

The check-ins reportedly make him feel like a "child" the magazine asserts, and it appears her reasons for being so worried also come from jealousy related to his relationship with his "sober coach".

The magazine claims that his dependence on the man is not helping things with their marriage, and that Kidman wants her husband to understand why she is feeling the way she does.

"Nicole has begged him to understand where she's coming from, and has even suggested couples therapy," the source said. "Keith isn't sure how their marriage can survive if she can't trust him."

However, it comes on the heels of the couple's 10th wedding anniversary, which they celebrated in June, and after other sources have said that they still made time to work on their marriage, and that they were still very much in love.

"They are madly in love and still make time to go on dates with each other. They both feel like they are soul mates and they don't take each other for granted," sources told Hollywood Life at the time.
