Last night, Halle Berry stepped out on the red carpet for the first time since revealing her pregnancy.  See pics of her with Michael Kors and get the deets on her new "Watch Hunger Stop" campaign inside...

Halle Berry showed off her emerging baby bump last night in a simple black Michael Kors dress as she posed in The Pool Room at the Four Seasons hotel for the United Nations World Food Programme.  Joined by Michael himself, she launched the "Watch Hunger Stop" philanthropic effort which will provide 100 meals to children through UN programs, funded by the sale of Michael's specially-designed "Runway" watch.  

Knowing that the effort could take her and Michael through Africa, Syria and Central America (where the meals will be distributed) Halle said, "I hope we go while I'm pregnant, so I can talk about prenatal care."

She added, "It's so important to me, being a mom, that I can help educate women on how important it is that when you have a healthy child, it helps set them up for life."

During a joint interview with Michael to promote the "WHS" effort, Halle gushed about her pregnancy saying,  

"I feel fantastic. This has been the biggest surprise of my life to tell you the truth. 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."

Sweet!

Fab mother and "Losing You" singer Solange Knowles stopped by to support Halle's efforts for children in need. Loving these sky-inspired Michael Kors "Samantha' pants and clear Alice+Olivia clutch-in-clutch.
