Halle Berry and Olivier Martinez looked like they were sharing a private joke leaving an LA art show yesterday. Olivier's been in town for the past week since Halle and Nahla welcomed him to the West Coast with a special happy birthday surprise. The pair stepped out for a lunch date before the Golden Globes Awards, though Halle decided to walk the red carpet solo in a short and sleek black gown. The best actress nominee didn't take home an award for her role in Frankie and Alice, but she was all smiles arriving at the star-studded afterparties. Her relationship with Olivier seems to going strong, as is her ex-husband's, Eric Benet, who recently announced his engagement to girlfriend of three years, Manuela Testolini.
