MY FIANCE HAS NAHLA'S BACK - HALLE BERRY

Halle Berry's fiance Olivier Martinez proved he's strong enough to carry the family ... or at least Nahla ... during a fancy dinner date in Malibu this weekend.

After hearing the good news about Halle's stalker being re-captured by authorities, the gang hit up Nobu Saturday night.

Nahla looked pretty comfortable with Olivier ... tightly embracing the guy as he carried her out to the car.

As TMZ first reported, Nahla has issues with the other man in her life ... her father Gabriel Aubry ... telling the L.A. Department of Children and Family Services she's scared of him. Gabriel is now only allowed to see Nahla with a monitor present.
