The 'Cloud Atlas' actress is pregnant with her first baby with Martinz, who said that their son would be a US citizen, reported People magazine.
"My son will be an American, but I remain French," Martinz said.
Berry, who already has daughter Nahla, five, from her time with ex-boyfriend Gabriel Aubry, recently revealed she is delighted to be expecting her second child.
"Nahla's really happy. Not long ago she asked God for a little sister, but I tried not to get her hopes up. At 46, I didn't know if I'd be able to get pregnant again," she said.
