Carrie Underwood Had Her Baby Boy on Monday

CARRIE UNDERWOOD gave birth to a baby boy on Monday . . . her second son with husband Mike Fisher.  They named him Jacob Bryan.  Their other son Isaiah is three.  Carrie’s 35, Mike’s 38.

They waited until yesterday to post the news on social media, writing, “Mom, dad, and big brother couldn’t be happier for God to trust them with taking care of this little miracle.  Our hearts are full, our eyes are tired and our lives are forever changed.”

They also posted three photos that feature each of them getting a turn to hold little Jacob.

The always-prepared Carrie set aside a few months to relax and spend time with her newborn son and the rest of the family.  Her Cry Pretty Tour 360 doesn’t pick up until May 1st.
