The new mom took to Instagram to share her first photo as a new mom, writing, "No time to fix the hair today. Headband to the rescue! #KeepItSimple @caliabycarrie."
In the pic, the country cutie is showing off her flawless face as she models a headband from her new fitness clothing line, CALIA by Carrie Underwood.
She might not have had much time to style her hair, but she still looks gorgeous!
The "American Idol" alum welcomed her son earlier this month, announcing the happy news on Twitter with a sweet pic of her little one.
"Tiny hands and tiny feet...God has blessed us with an amazing gift! Isaiah Michael Fisher - born February 27," she captioned the photo.
This is the first child for Carrie, 31, and husband Mike Fisher, 34.
The star recently opened up to ABC News about the moment she and her hockey player hubby found out their baby's gender. The couple had their doctor write the answer on a piece of paper and put it in an envelope, but they both already had a feeling on what it could be.
"It was just the two of us in a nicer setting, but we both knew," she said. "So, that was just confirming our suspicions. We didn't really speak of it before, 'cause we were both just like, 'Whatever. It's all good.' But we knew it was a boy."
Congrats to the couple again -- we can't wait to see more of this little guy!
