Mama Meester Alert!

Well this is news that probably went happy coast to coast earlier this week.

The ultimate Upper East Side girl and her cool-O.C.-guy husband are expecting a baby.

Yes, congratulations are in order for Leighton Meester and Adam Brody now that they are set to become parents...some time later this year? This much was beyond-evident after some paparazzi caught up with the erstwhile Gossip Girl looking preggers while out and about last weekend.
