It's already been three years since Kelly Clarkson and Brandon Blackstock tied the knot in a stunning and intimate ceremony in Tennessee, and the pair seem to be falling more in love every year. The "Piece by Piece" singer posted a photo of their small celebration on Twitter on Thursday, in which they carved their initials into a tree. "We got that young love," she wrote. "Happy anniversary @BBlackstock We remembered this year." In addition to their sweet romance, they also share one adorable family. Kelly and Brandon welcomed daughter River in June 2014 and son Remington in April 2016. Brandon also has two kids, Seth and Savannah, from a previous relationship.
