Nicole Kidman and Keith Urban's relationship has been reported to be in strain lately.

Nicole Kidman and Keith Urban got married in 2006 and had two daughters together named Sunday Rose and Faith Margaret. However, it seems that Nicole Kidman and Keith Urban's work pressures are tearing their marriage apart in these days.

An insider recently told British magazine Grazia about the couple: "Tensions are reaching boiling point within their marriage. It's no secret that they're spending increasing periods apart, and Keith's close friendship with J-Lo won't have helped, especially as both Jen and Keith are returning to American Idol next season."

Since 2013, country music star Keith Urban has been busy as one of the judges for the reality music competition American Idol and also served as a mentor for The Voice Australia. Meanwhile, A-list actress Nicole Kidman is having a hard time with her film career lately as her most recent film "Grace of Monaco" received poor reviews from film critics. She portrayed the glamorous actress, fashion icon and later the most loved Princess of Monaco Grace Kelly and the film tells the love story between her and Prince Rainier III of Monaco.

The insider adds: "Nicole's had a lot on her plate with the panning that Grace of Monaco got, and it won't be helping if she no longer feels she can lean on Keith. It's fair to say communication doesn't seem great between them, to the extent that they're decreasingly talking face-to-face. Friends are wondering whether their eighth wedding anniversary will be their last."

However, Nicole Kidman recently spoke that if she ever given the choice between love and career, she'll definitely choose the former. She said, "I have never had to; I would, absolutely. I wouldn't even think twice about it because I would hope there is something else I can do, and I would find something else to do. I think love is the core emotion, and I have certainly existed without that in my life, and it's a very empty life."
