Halle Berry’s fiance Olivier Martinez to testify in Nahla child custody trial

New York: Halle Berry has a key witness she`s going to call to the stand to support her bid to take Nahla to Paris -- her fiance, Olivier Martinez.

Martinez, who is a famous actor in his native France, will be able to make a strong case supporting Berry`s desire to move her young daughter Nahla to Paris, the site explains, because he is very familiar with France`s strict paparazzi laws, a leading daily has reported.

In France, taking photos of young children is firmly frowned upon, and Berry insists that these stricter paparazzi laws would help her feel safer when she`s out and about with young Nahla.

Berry has also called upon other bold-faced names to assist her in her custody case, including Hollywood pal Salma Hayek, who is married to French billionaire Francois-Henri Pinault.
