FIVE is the number for this FIFTH day of the work week for some celebrity birth and pregnancy stories around the web involving baby number FIVE. 

But in this era of blended families and separation and divorce so common, there are 15 parents in this story. Read on:

In 2011, after Joni was born, Brown joked that he planned to keep on trying until he got his boy. I guess Shelly was down for the plan! (smile)
