With the recent news that Nicole Kidman and Keith Urban are heading for divorce after 12 years of marriage, fans are desperate to find out what could have possibly led this picturesque Hollywood couple astray. As it turns out, there's one A-list celebrity to blame — and it's not another woman!

An insider has told Life & Style, "Keith has moved out of the family home he shares with Nicole after a string of arguments. He’s been staying at a five-star hotel in LA." The source added that the main cause of their arguments is Keith’s growing friendship with John Mayer, which may be surprising to some. "Nicole tried to put a ban on Keith spending time with John because she’s convinced he’s a bad influence on her husband," the insider said.

As far as what makes John a "bad influence" remains to be seen. We do know that John celebrated one-year of sobriety back in October, according to People, so partying is presumably not the issue. Additionally, the two musicians haven't formally collaborated since 2013's "Don't Let Me Down." John may just be the scapegoat Nicole has been looking for!

Apparently, the couple has been struggling for quite some time. Back in September 2017, Vernon Rust — a former friend and collaborator of Keith's — suggested that the country singer's marriage to Nicole was a complete sham. They would "attend a 'pond draining' if a red carpet and a photographer were gonna show up," Vernon wrote in his tell-all novel Fake News.

Through the support of friends and family, the two are taking time to heal themselves for their shared daughters — Sunday (9), and Faith (7). "Keith’s been leaning on his brother, Shane, and has a group of close childhood friends who he’s been talking to daily," an insider explained.

Nicole, on the other hand, has been confiding in longtime friend Naomi Watts. Naomi is no stranger to divorce, as she ended her 11-year partnership with Liev Schreiber back in 2016. "Naomi knows only too well how painful it is to go through this,” the insider explained. “She’s been advising and supporting Nicole through everything.”
