Melanie Griffith and Antonio Banderas are separated after 18 years of marriage. They claim their divorce will be handled amicably. Melanie apparently already prepared for a custody battle, but this fight does not involve the couple's daughter. Their daughter, Estella, will be turning 18 in September, so there will not be a lengthy custody battle over her. Melanie has asked the court for primary custody, but this is seen to both parties as a non-issue. Melanie is however calling herself a better parent to the couple's three dogs. Melanie has apparently even said it would be in the dog's "best interest" to live with her, a standard which is usually reserved for child custody matters.
