Pregnant Halle Berry Reveals Baby Bump In Sexy Black Dress (PHOTOS)

Halle Berry is just the latest celebrity to enter the pregnancy club.

The "Cloud Atlas" actress, who announced that she was expecting a baby with fiancé Olivier Martinez last Friday, posed on the red carpet with American designer Michael Kors for their Watch Hunger Stop campaign on Saturday.

The actress looked sexy as always and showed a barely visible baby bump in a clingy black dress.

"This has been the biggest surprise of my life, to tell you the truth," Berry told Us magazine about her pregnancy. "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."

Over the weekend, the 46-year-old hung out with friends in New York City and showed off just a glimpse of a bump underneath an open coat.

This isn't Halle's first child; the Oscar-winner gave birth to daughter Nahla Ariela Aubry in 2008 (the father is Canadian model Gabriel Aubry; the couple broke up after five years in 2010).

Halle and Martinez, who is also an actor best known for his role in the 2002 film "Unfaithful," have been dating since 2012.

If Halle keeps up these hot looks, we can't wait to see what happens when her bump pops. Let's just hope she doesn't wear harem sweatpants.
