Their daughter may not even be a year old yet, but Halle Berry and Gabriel Aubry love parenting so much they're apparently thinking about giving baby Nahla a little brother or sister sometime soon!

"Yeah, we are working on that," Gabriel told Us magazine when asked about adding to his family with Halle (pictured above at Monday night's ELLE women in Hollywood tribute).

Gabriel says his Oscar-winning lady is made for motherhood. "She is unbelievable!" he said. "She is the best mom that anybody could ask for -- or wish for."

And as far as his fatherhood experience? "I had no expectations so everything is a surprise," he said. "There is no best part. Everything is amazing!"
