According to TMZ and Page Six, the couple started living separately in the early summer, when Keith left the house in Nashville and bought other real estate.
Nicole Kidman has taken care of his two daughters Sunday Rose (17 years old) and Faithaged (14 years old), trying to keep the family stable since Keith left. The actress did not want to break up and tried to reconcile.
A source said that Antonia's younger sister and the Kidman family were her support.
Previously, in June this year, the actress still posted a photo celebrating her 19th wedding anniversary on Instagram, but also during this time, Keith attracted attention when he suddenly interrupted an interview when asked about his wife's hot scene in "A Family Affair".
Nicole Kidman and Keith Urban met in 2005 and got married in 2006. Previously, Nicole had been married for 11 years to Tom Cruise and adopted two children Bella and Cooper.
Currently, the two have not commented on whether they are going to divorce or not. The actress has just finished filming Practical Magic 2, while Keith is on a tour.
