After 18 years of marriage, Melanie Griffith has filed for divorce from third husband Antonio Banderas.

According to TMZ, who has obtained the legal documents, Melanie cites irreconcilable differences as the reason for the split and requests both child and spousal support.

The 56-year-old actress also asks for joint legal custody of the couple's daughter Stella, though any custody agreement will be moot when she turns 18 in September. The divorce documents reportedly don't list a date of separation.

This will be Melanie's fourth divorce after she married first husband Don Johnson twice as well as actor Steven Bauer. She has two children from those marriages, including actress Dakota Johnson.

This will be Antonio's second divorce following his separation from first wife, Ana Leza. The couple had no children together.
