Halle Berry

Halle Berry's baby bump was visible under a figure-hugging Roberto Cavalli gown for the premiere of her film The Call in Buenos Aires yesterday. The news broke last week that she is expecting her first child with fiancé Olivier Martinez, but her pregnancy has not deterred her from keeping busy. Halle put her baby bump on display when she popped up in the Big Apple to attend the United Nations World Food Programme event on Saturday.

Halle is reportedly expecting a baby boy, which fulfills her 5-year-old daughter Nahla Aubry's dreams of becoming a big sister. During a stop on The Wendy Williams Show last Fall, Halle foreshadowed the joyous occasion by revealing Nahla's wishes for a sibling, saying, "That's the thing. [My daughter is] asking me. Every night we pray to God, and she's so sweet. She says, 'God, please bring me a bunk bed and a baby sister.' And I say, 'I can do one of those things, I know for sure! The other one we have to keep praying on.'"

Halle Berry made her first public appearance since her pregnancy news at a United Nations World Food Program event in NYC on Saturday. She was joined by Michael Kors, who cohosted the event with Halle, as she displayed her baby bump in a black dress. At the event, Halle revealed that she was surprised to find herself pregnant again. She said, "I thought I was kind of past the point where this could be a reality for me. So it's been a big surprise and the most wonderful." This will mark Halle's second child — she is mom to 5-year-old Nahla — and her first baby with fiancé Olivier Martinez.

Michael Kors hosted a seriously stylish dinner in honor of Halle Berry, as she joins both the designer and the United Nations World Food Programme to fight world hunger. To fete the cause, Solange Knowles, Doutzen Kroes, and Hilary Rhoda were among the other guests in attendance — in a cool mix of Kors wares, of course. Meanwhile, the lady of the hour showed off her growing baby bump in a black body-hugging Michael Kors dress, a Michael Kors Watch Hunger Stop campaign watch, and ankle-strap sandals to toast the occasion.
