Halle Berry stopped by a friend's house in LA yesterday wearing her workout gear and carrying a wrapped gift. The actress and her boyfriend Olivier Martinez enjoyed a night on the town at a party hosted by Dior on Wednesday. It was the second evening out in a row for Halle, who was also honored at the Costume Designers Guild Awards on Tuesday with the Lacoste Spotlight Award. She was in great spirits on stage, though in her personal life, her custody battle with Gabriel Aubrey is back in the headlines. Halle will turn the tables at Sunday's Oscars, though, as she gives out a statuette. She's one of several celebrities, including newly announced stars Scarlett Johansson and Russell Brand, who have signed on as presenters for Hollywood's big night. Details about who will present which honors are still mostly secret, but Scarlett revealed that she'll be taking the stage with "dreamboat" Matthew McConaughey.
