It's hard to tell if Halle Berry has the pregnancy glow or just the usual Halle Berry glow — but the girl looks good.

The proud mom-to-be showed off her baby bump on Monday in Buenos Aires at the premiere of her new film The Call.

Check out the photo here.

Leave it to Catwoman to still be the hottest mama on the red carpet at 46!

Halle recently admitted she's as surprised as anyone to be carrying her second child at this age. She also has diabetes, which just adds another potential health wrinkle, but she takes care of herself and has access to the very best medical care.

All we can do is wish her well — and watch her progress via beautiful photos like this!
