The singer announced the news on Twitter Tuesday morning. "Tiny hands and tiny feet," she wrote. "God has blessed us with an amazing gift! Isaiah Michael Fisher - born February 27." This is Underwood's first child with husband Mike Fisher.

The American Idol alum also took to social media to announce her pregnancy back in September when she shared a photo of herself with her two pups donning separate shirts that read "I am going to be a Big Brother" and "I am going to be a Big Sister."

Best wishes to the couple and their newborn!
