Kelly Clarkson has shared a stunning new photo of her growing family — including newborn son Remington.

The pop powerhouse, whose husband is music manager Brandon Blackstock, took to Instagram to post a pic of the couple's beautifully blended family, including 2-week-old Remington, or "Remy" as his folks call him; daughter River Rose, 22 months; and big half-brother and half-sister, Seth and Savannah, Blackstock's children from his marriage to Melissa Ashworth.

The photo finds all four kids looking dapper in grayish hues as Savannah gently cradles little Remy. Clarkson captioned the pic "The von Trapps ain't got nothin' on us ha!" in reference to the many singing siblings from "The Sound of Music."

It's been a busy month for the original "American Idol" winner, who turned 34 on April 24, just one day after sharing the first pics of Remy with the world.

But her sweet new baby boy isn't the singer's only offspring creating a buzz. Clarkson recently announced her upcoming children's book "River Rose and The Magical Lullaby" inspired by her daughter. The book, which will be published by HarperCollins in October, follows a fictional character based on little River Rose who travels the world meeting animals and having adventures.

Congrats to the whole family!
