See Halle Berry’s Growing Baby Bump

Now that the world knows she’s pregnant, Halle Berry has just decided to let it all hang out.

The 46-year-old beauty showed off her growing baby bump with pure mommy joy Monday night at the premiere of The Call in Argentina, where she wore a gorgeous one-shouldered Grecian dress.

Naturally, the mom-to-be was all smiles on red carpet (who wouldn’t be if you got knocked up by Olivier Martinez?) and at one point even clutched her bump for the cameras.

This is the second child for Berry. She has a daughter, Nahla, 6, with ex-boyfriend Gabriel Aubry.

Berry has been dating Martinez since last year.

Berry won an Oscar in 2002 for her performance in Monster’s Ball, despite formidable competition Nicole Kidman, Sissy Spacek, Renee Zellweger — hell, even Judi Dench.
