TMZ.com reports that Halle Berry, 45, has arrived at court for her showdown with baby daddy Gabe Aubry, 35.

As you know, Halle’s nanny quit last week after Gabe flew into a rage and slammed her against a door — while she was holding Nahla in her arms.

A previous court order stipulated that a nanny must be present at all times while Aubry has custody of Nahla. But Aubry kept Nahla out of school last week without informing the nanny who went to the school to pick her up.

A police report was filed by the nanny accusing Aubry of assault.

Halle Berry has just arrived at court, where she’ll ask a judge for an order prohibiting her baby daddy, Gabriel Aubry, from having ANY contact with 3-year-old Nahla until the child endangerment investigation against him is resolved.

As TMZ first reported, the LAPD is conducting a criminal battery and child endangerment investigation after Gabriel allegedly pushed the nanny with Nahla in her arms. And before the alleged pushing, the nanny says Gabriel screamed at her and hurled a racial epithet. In addition, we’ve learned the L.A. County Dept. of Children and Family Services is also conducting a child endangerment investigation.

TMZ has learned more about what nanny Alliance Kamdem has told the cops. Law enforcement sources tell us … Kamdem claims Gabriel repeatedly yelled and cursed at her, often while Nahla was present. Kamdem also says it got so bad … Gabriel would make her sit in a corner in his condo until he called for her.

Kamdem also claims Gabriel often yelled at Nahla, causing the child to cower and cry. And she told police … when Nahla had a rash he refused to treat it.
