Don't cry for Halle, Argentina! Halle Berry announced she's expecting again to widespread surprise last Friday, and for now, the Oscar-winning actress, 46, is happy to share her pregnancy glow with the world. At the premiere of her thriller The Call in Buenos Aires, Argentina, the star and Revlon spokesperson looked typically stunning in a regal, one-strapped purple gown featuring silver and gold embellishments.

On the red carpet, Berry happily caressed her growing baby bump in the flowing dress, which featured a fitted bust that emphasized her slightly fuller cleavage. Engaged to the baby's dad-to-be Olivier Martinez, Berry, completing the look with diamond-drop earrings an silver strappy heels, serenely smiled on the red carpet.

Among those shocked by the 46-year-old stunner's second pregnancy? Berry herself! "This has been the biggest surprise of my life, to tell you the truth," she told CNN's Alina Cho. "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."
