The fourth time wasn't the charm, either -- Melanie Griffith has filed for divorce from Antonio Banderas.

Melanie, who's already been divorced three times, had been with Antonio for 18 years. According to TMZ, the split is amicable, but she's asking for both spousal support and child support. The latter is pretty much moot, however, since their one daughter is almost 18 years old.

It'll take a little while to untangle their estates, as the couple owns lots of property in the U.S. and Spain.
