In addition, the brunette beauty opened up about the milestone occasion to People and exclaimed that the SoCal-based event was "so much fun."
"My family made me feel like a queen, and my baby girl is going to be decked out in the cutest clothes ever — she even got a mermaid outfit," she revealed. "We all stuffed our faces with a cake that was too pretty to eat, and everyone had to guess how big my belly is — I am ALL belly right now. I was so happy to spend time with everyone before things get super busy." You can say that again, Drina!
