Halle Berry and Olivier Martinez were arm in arm for a walk around Sunset Plaza in LA yesterday. They've been together all week with multiple day dates including a romantic lunch. Halle's weekend was all about Nahla, though, as they spent their sunny days on the beach in Malibu. Halle wore a bikini while Nahla played in the sand and checked out the tide pools. Filming for Halle's ensemble project New Year's Eve is still going on in NYC, though it looks like Halle already wrapped up her time on set when she was briefly in the Big Apple last month.
