OK, sweetness! Kelly Clarkson shared a new photo of her growing family, including her newborn son, Remington, her daughter, River, and her stepkids with husband Brandon Blackstock, Savannah and Seth, on Tuesday, April 26. 

The proud mom, who debuted photos of her baby boy Remy on Saturday, April 23, posted a new colorful portrait taken by Archetype Studio photographer Koby Brown, of the little one with his older siblings on Wednesday.

"Okay last pic! Promise," Clarkson tweeted on Tuesday. "#andthentherewerefour #familyband The von Trapps ain't got nothin' on us ha!"

In the picture, Savannah, 14, cradles baby Remy in her arms while seated on a plush sofa bed in a lush green garden. Seth, 8, poses on the opposite side of the bed and dotes on his kid sister River Rose, 22 months, who beams at him.

Blackstock shares his two eldest kids with his ex-wife, Melissa. Clarkson, meanwhile, just welcomed their youngest on April 12. 

“Our little baby boy has arrived!!” the "Piece by Piece" singer tweeted, alongside a black-and-white pic of Blackstock holding the teeny infant in his arms. “Remington Alexander Blackstock was born 4/12/16 & he is healthy & we couldn’t be happier or more in love!"

Family life suits the singer well. "So 4 my birthday I have my newborn n my hands, @GameOfThrones starting 2night & I just found Meryl has a new film coming out! #bestbirthday," she wrote on Sunday, April 24, as she turned 34.
