It looks like the rumours were true, Nicole Kidman has filed for divorce from Keith Urban after 19 years of marriage.

The Tennessean is reporting that she filed in Davidson County on Tuesday. The filings included a marital dissolution agreement and a parenting plan with a child support worksheet. The Marital Dissolution Agreement states that they "experienced marital difficulties and irreconcilable differences." Several sources have been quoted giving a number of reasons the marriage ended including that they grew apart because work kept them separated, they've been living apart since the start of summer and that Keith has "been making questionable choices for some time now." No official word on the cause of the split has been given.
