Look at this unbelievable interchange (below), starting with The Donald's initial tweet:
OMG!!! Baby bump alert: Leighton Meester stepped out with a baby bump and she's super adorbs!
This is such an exciting time for the couple, seeing as it's Leighton and Adam's first child!
While we're shocked the actress is preggers, it's no surprise the duo waited until she was showing to make an announcement!
They are pretty secretive with their personal life! Remember when they secretly got married and left it at that? LOLz!
Here's to a happy and healthy pregnancy, girl!!
