Mena Suvari has filed for divorce after only 18 months.

The actress, who wed Simone Sestito in a private church in Vatican City, was actually engaged to the concert promoter longer than she was married.

In her divorce docs filed Friday in Los Angeles County Superior Court, Suvari states that the pair separated November1. She gave "irreconcilable differences" as the reason for the split, and asked the court not grant Sestito spousal support.
