Stunner, Halle Berry, is learning French so her unborn baby will grow up bilingual. The Monster's Ball star has started placing 'Post-It' notes all around her home, so she is surrounded by words for every day objects. Her French-Canadian boyfriend Gabriel Aubry has even started talking to the tot in his French tongue - using his girlfriend's belly button as the microphone. Asked by chat show host David Letterman if Gabriel was talking to her bump, Halle replied: "He's doing that in French because his first language is French - he's French-Canadian. He talks into the belly button and calls that the microphone. "I have pressure now to learn French, because we want this kid to be bilingual." Halle said she was finding it hard to learn a new language so late in life, but revealed she had come up with tricks to help her. "What I'm doing is putting Post-It Notes all around the house, because that's one way that Gabriel learned English," she said. "He Put Post-Its all around, so I've got them everywhere."
