Halle Berry has been ordered to pay her baby daddy $20,000 a month in child support.

Her ex, Gabriel Aubry, asked a Los Angeles judge in May to award him the large sum so he could raise the former couple's daughter Nahla properly -- and now Halle will have to shell out nearly quarter of a million bucks a year.

The next fight in their ongoing custody case will be whether Halle can move with Nahla to Paris.
