Nashville, Jan. 7 -- Nicole Kidman and Keith Urban are divorced and legally single, ending the 19-year marriage of one of entertainment's most prominent power couples.

A Nashville, Tennessee, judge issued an order at a hearing Tuesday dissolving the marriage of the Oscar-winning actor and the Grammy-winning country singer.

Judge Stephanie J Williams said in a court filing that the couple's settlements on splitting assets and child custody are sufficient, and granted them the divorce.

Williams wrote that "there exist such irreconcilable difference between the parties that would render continuation of the marriage impractical and impossible."

Both Kidman and Urban waived their right to appear at the hearing.
