Picking a baby name is always a highlight when welcoming a new child into the world.

But seems that instead of grabbing a traditional baby name book for their second child, actress Jaime King and husband Kyle Newman went for a geography book instead.

On Thursday, Newman posted a sweet message about their newborn son on Twitter and in it he revealed the name of the couples' second child.

"So happy Leo Thames is in the world," Newman tweeted.

E! News reported that Leo Thames is also the name of England's most famous body of water.

Baby Leo, the godson of mega pop star Taylor Swift, was born July 16. The couple announced his arrival July 20 via an Instagram post that features a topless King alongside Newman and their first child, son James Knight, but no baby.

The couple was flooded with warm wishes from famous friends such as Diane Kruger, and Sarah Hyland.

Hyland tweeted "Just got home from a long day at work & the most special 4 hours with @Jaime_King @kyle_newman and their beautiful new baby I love you all."

Tamera Mowry-Housley, who also became a mom to a second child, a baby girl, earlier this month, sent her congrats to the couple.

King first told Just Jared the name of baby No. 2 saying, "Kyle​ ​and I named our second son ​Leo Thames Newman. Our family couldn't be happier welcoming ​​​​​another little angel into this world. Thank you for ​all of the support and well wishes."
