Salma Hayek is Halle Berry’s secret weapon in her child-custody war with ex Gabriel Aubry. Hayek, who’s wed to French billionaire François-Henri Pinault and spends a lot of time in Paris, has filed a declaration to the LA judge hearing the custody battle over Berry and Aubry’s daughter, Nahla, saying France is a safer place for celebrities and their children because of tougher paparazzi laws, according to reports. Berry is fighting to relocate Nahla to her fiancé Olivier Martinez’s native France. Berry, Hayek and their French partners dined at LA restaurant Little Door Wednesday night, sparking another paparazzi crush.
