Carrie Underwood shares sweet tribute to newborn son in a move that many may not have noticed

Carrie Underwood nearly pulled a fast one on fans as she quietly changed her Twitter bio to include a mention of her new son, Jacob Bryan.

The country singer, who gave birth to her second son just three weeks ago, updated her bio earlier this week. Some didn't catch it at first, but then her vigilant fans took notice.

They reposted a screenshot of the 35-year-old's bio which acknowledged her husband Mike Fisher as well as her two dogs Ace and Penny. The fan post is found below.

The new bio read:

“Mike’s wife, Isaiah’s and Jacob’s mom. Also, mom to fur babies Ace and Penny Jean. Blessed and grateful! The official twitter account for Carrie Underwood.”

Fans' reactions were quite endearing and they loved it overall. They also appreciate the singer's willingness to share personal parts of her life.

On January 23, Underwood posted a few intimate photos of her and the family holding newborn Jacob Bryan.

She wrote in the caption:

"Jacob Bryan Fisher entered the world in the wee hours of the morning on Monday...his 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. Life is good."

Fisher, a former ice hockey pro, also took time to post a message on his Instagram account:

"The last few years has has had its challenges and it makes this moment even more sweet! We didn’t know if Izzy would ever have another sibling but we learned through it all that God is in control and his timing is perfect! He is good all the time even in the difficult times that are hard to understand. #grateful #miraclebaby."

The family of four have mostly remained off of social media since they welcomed Jacob Bryan last month. Fisher, however, shared photos of son Isaiah playing hockey late last week.

Their bonding time was a nice change from all the baby time the family has been having, though it's undoubtedly welcomed.
