The couple threw a baby shower in Malibu on Saturday, which included a massive flower display introducing their soon-to-be daughter's name, Mia. Thicke and Geary will be welcoming their first child together in March. This will be the singer's second child, he's already a father to 7-year-old Julian from his previous marriage with Paula Patton.
23-year-old Geary proudly displayed her bump while wearing a flowing Dolce & Gabbana dress with her 40-year-old baby daddy by her side. "Today was perfect," she captioned the photo.
The party included tons of friends, including Paris Hilton -- and like any party -- the clean up was not fun.
