Jen and Ben headed south to Miami to join the Damons to speak at a fundraiser for Obama on Saturday night. The BFF foursome kept things simple in black and white but there was no hiding those glowing grins and growing bellies. People reports that Jennifer gave a "witty, clever and funny" speech followed by Ben and Matt's more serious ones.

Matt Damon had his arms full with adorable Isabella and her baby doll, but was happy to pose with Luciana on his way out of Miami Airport yesterday. Now that he's back in warmer climates after working on Green Zone in the UK, it's probably time to ditch the beanie for a more spring friendly Red Sox hat. His little girl is looking so grown up these days, and hopefully she's ready to be a big sister — from the looks of Luciana's growing bump, they won't have to wait much longer for their new addition.
