Jennifer Garner hid her pregnant belly very effectively while posing at the Pink Party event held in Santa Monica to support Cedars-Sinai Women's Cancer Research. She wasn't nearly as dressed-up as host Kate Beckinsale in girly pink ruffles (check out the thumbnails for a peek!), but she's pregnant and can do what she wants. Here, here!

There's more stunning Jennifer Garner in the thumbnails, as well as Julia Louis-Dreyfus, Kate Beckinsale, and Lori Loughlin.
