*TMZ.com is reporting that Halle Berry and her boyfriend Gabriel Aubry have ended their five-year relationship and have already reached a temporary custody arrangement for their two-year-old daughter Nahla.

The actress was smiling for cameras on the red carpet yesterday at DKMS’ 4th annual gala for Linked Against Leukemia in NYC, but a source tells TMZ that Halle has been going through private anguish becuase the couple has “clearly been having problems” for a while now.

Although the two have not been to a lawyer to formalize a custody arrangement or a property settlement agreement, Halle and Gabriel are clearly separated and have chosen to seek a custody arrangement for Nahla on their own.

“We are told by sources close to the situation that Halle and Gabriel are ‘working well together’ and are handling parental duties without conflict,” TMZ reported. “We are told the long-term plan is to share custody but nothing has been formalized in writing.”

Currently, the two have a “very short-term custody arrangement,” TMZ reports. “They have renewed them each time they have expired and are still working under a short-term agreement but no permanent agreement has been struck.”
