Carrie Underwood has welcomed her second child [2]! The singer shared the news of her son's [3] Jan. 21 birth on Instagram, along with his adorable name: Jacob Bryan Fisher.

Although Carrie and Mike Fisher's first child, Isaiah, has a name that ranks pretty high on the Social Security Administration's list of popular boys' names [4] — it's been hovering between No. 39 and 47 on the top names list since 2000 — Jacob is actually a much more popular name [5]. Between 2000 and 2012, Jacob was the No. 1 boys' name [6], and though it's dropped to No. 10 as of 2017, it's still trendy as ever!

Plus, both popular names [7] sound amazing when put together — Isaiah and Jacob Fisher rolls off the tongue, doesn't it? Congratulations, Carrie and family!
