Carrie Underwood and husband Mike Fisher welcome second baby boy, Jacob Bryan

The 35-year-old star revealed on social media that she welcomed newborn Jacob Bryan Fisher with hockey player husband Mike Fisher on January 21.

Country singer Carrie Underwood is celebrating the birth of her second child. The 35-year-old star revealed on social media that she welcomed newborn Jacob Bryan Fisher with hockey player husband Mike Fisher on January 21. Along with a photo gallery of herself, Fisher, and her 3-year-old Isaiah Michael with the newborn, the singer wrote: "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!" 

The proud mother added: "Our hearts are full, our eyes are tired and our lives are forever changed. Life is good…" PEOPLE reported that the infant's arrival into this world comes months after Underwood had revealed in August last year that she and 38-year-old Fisher were expecting their second child. The singer then announced the sex of the baby during the opening of the CMA Awards in November last year, which she co-hosted with singer Brad Paisley.

But before she became pregnant, there a brief period where the singer had found herself in a difficult situation. In November 2017, she had a fall on the steps of her home in Nashville as a result of which she received 40- 50 stitches on her face and even underwent surgery for a broken wrist. The scars made her quite anxious. Aside from this, she also shared that she suffered three miscarriages from 2017 to 2018. Underwood appeared on CBS Sunday Morning in September last year for an emotional interview.

The singer opened up about her struggles with fertility during the interview. The star explained her reaction to the heartbreak by saying: "My son, Isaiah, is the sweetest thing. And he’s the best thing in the world. And I’m like, 'If we can never have any other kids, that’s okay because he’s amazing'. And I have this amazing life. Like, really, what can I complain about? I can’t. I have an incredible husband, incredible friends, an incredible job, an incredible kid. Can I be mad? No."

Underwood spoke to Redbook magazine in August 2018 about her emotional year and she reflected on the life-changing fall that she suffered before the months that followed it. She said: "It was … a very soul-searching year for me. There were some personal things that happened. And I had the accident and all of that to get through … and just life. Life is full of ups and downs, and I might have had a few more downs than ups last year."

When talking about her older son, Isaiah, transitioning into a big brother now, the winner of American Idol season 4 told Jimmy Fallon in September last year that the child still probably doesn't know the new role he has to play. She said: "I don’t think for real he does. He’ll be really sweet and talk to my belly and kiss my belly. He’s the sweetest little boy. But no kid can really know that their life is going to change … He’ll have to share Mommy."

Underwood released her latest album, 'Cry Pretty', on September 14 before hosting the CMA Awards for the 11th time. She is on maternity leave at the moment before kicking off her tour, supported by Maddie & Tae and Runway June, on May 1.
