Keith Urban shocked fans this week by changing the lyrics to a song about Nicole Kidman just days before the pair announced they were splitting after 19 years of marriage. Kidman, 58, filed for divorce from her country music star husband on Sept. 30, citing irreconcilable differences as the reason for the split.

They have a combined net worth of $325million.So when it comes to dividing up Nicole and Keith's assets, the Hollywood couple have a lot at stake.
