In unfortunate news, Christine Costner, the wife of popular actor Kevin Costner, has filed for divorce after more than 18 years of marriage. The filing cites irreconcilable differences as the grounds for divorce, and Christine is reportedly not seeking any spousal support. The couple shares three children together, and Kevin has four other children from previous relationships. A representative for Kevin has confirmed the news and has asked for privacy for the family during this difficult time. The pair got married in 2004 at Kevin’s Aspen, Colorado ranch.
