Melanie Griffith has filed for divorce from Antonio Banderas after 18 years of marriage.

The “Working Girl” star, 56, is asking for child support and sole physical and joint legal custody of the couple’s daughter, Stella, who turns 18 in September, reports TMZ.

Griffith cited irreconcilable differences as the reason for the dissolution of her union with the 53-year-old Spanish heartthrob.

On Thursday, the couple stepped out together at the AFI Tribute to Jane Fonda in Los Angeles.

This will be the actress’ fourth divorce, though she’s only been married to three different men. In addition to Banderas, she was married to actors Steven Bauer and Don Johnson (whom she married twice), with whom she has a daughter, Dakota Johnson, who will star in the upcoming “50 Shades of Grey” adaptation.

Griffith and Banderas met on the set of 1995’s “Two Much” and married in May of the next year.
