Halle Berry  smiled big for the cameras at the Rio de Janeiro premiere of The Call on last night. She flaunted her baby bump in a sexy lace cutout gown for the cameras and stopped to chat with a pal on her way inside the screening. Halle has bared her pregnant belly  on the red carpet multiple times since announcing the news last week. She attended a United Nations World Food Program event over the weekend and then headed overseas to start promotions for her latest film. Halle already stopped in Buenos Aires and attended a photocall in Brazil yesterday.
