Stefani had celebrated her pregnancy with a baby shower with stars such as Jessica Alba, Nicole Richie and Gwyneth Paltrow earlier this month.

Once again sharing photos through Instagram, the singer posted pictures of everything from the cake to a donut stand with "BABY" spelled out in front of it.

She previously expressed concern over how busy her life had become during a 2012 interview with Marie Claire saying, "I was definitely swimming upstream trying to balance everything that's been going on with having kids and a family. There's no way to do all these things."

Well, we hope they've got that under control.

Apollo joins his two brothers — Kingston, 7, and Zuma, 5.
