Nastiest Celebrity Custody Battles

By
Hollywood isn't all red carpets and champagne -- it's also the land of brutal breakups, which often lead to custody battles. From Mel Gibson and Oksana Grigorieva to Britney Spears and Kevin Federline we're taking a look at some of Tinseltown's ugliest custody disputes.
In 2010, fans heard another side of Mel Gibson in recordings of the movie star's caustic rants directed at ex Oksana Grigorieva. The estranged couple came to an agreement regarding their daughter Lucia that reportedly cost Gibson some $5 million.
Two years after their divorce filing, Kelsey Grammer and Camille Donatacci recently came to an agreement over their two children that enables both parents to spend equal time with the kids.
And in one of Hollywood's most expensive divorce cases, Britney Spears lost custody of her children to ex Kevin Federline, whom the singer reportedly has to pay $20,000 a month in child support.
