After a seemingly peaceful period of time the nasty custody battle is back on between Halle Berry and Gabriel Aubry, over their daughter Nahla.

Accusations are flying fast and thick as Halle claims her baby daddy broke the rules of their custody agreement - even going so far as to allege Gabriel has been negligent in his care of the three-year-old.

As Breaking Celebrity News previously reported Halle was back in court this morning, along with her powerhouse attorney Laura Wasser, who presented the custody judge with a thick dossier detailing all of Aubry's alleged wrongdoings.

A source close to the situation tells Breaking Celebrity News that trouble has been brewing over the past few weeks and that the situation between the ex-couple has been getting nastier by the day.

"Halle has been coming down hard on Gabe recently," the source says. "If he drops off Nahla just five minutes late or is not exactly on time when he picks her up, he gets  it in the ear, big time.
