Halle Berry and her daughter, Nahla, stuck together on Friday to grocery shop at a Bristol Farms in LA. Nahla stayed home yesterday, though, when Halle stepped out for a lunch date with her boyfriend, Olivier Martinez. It seems things are going great for Halle and Olivier, who first showed off their romance last September after working over the Summer on the movie Dark Tide. The Berry girls are home again in California following a short stint earlier this month in NYC, where Halle was shooting New Year's Eve. They were back in time to celebrate Nahla's big third birthday on the 16th, and Halle threw her special girl a party complete with a bouncy castle on the beach.
