The adorable photo features 2-week-old Remington being cradled by stepsister Savannah, while Clarkson's 1-year-old daughter River Rose is being watched by stepbrother Seth. Seth and Savannah are the children that Clarkson's husband Brandon Blackstock had prior to their marriage.
Clarkson has been open about how much she loves her family, which is in stark contrast to the complicated relationship she's had with father in the past, who she sings about in her emotional hit, "Piece by Piece." She gushed to Ryan Seacrest about her husband and the couple's relationship with their kids during a radio interview in February.
"Watching my husband love on his daughter all the time, you know, go to her events and just be there and, like, be present is, like, hard to watch but beautiful to watch," Clarkson said, fighting back tears. "But it's awesome because I know that my kids are going to have that."
