Granger Smith Says Son Lincoln, 7, 'Can't Get Enough' of 1-Week-Old Baby Brother Maverick Granger and Amber, 39, who are also parents to daughter London, 9, and son Lincoln, 7, welcomed their son Maverick on Aug. 20. Since welcoming their fourth child, Amber has addressed the "hurtful" comments she and the country singer have received about their late son River. In an Instagram Story last month, Amber shared several screenshots of criticism she had received, including an accusation that Amber and Granger were replacing River with their newborn baby. "I never like to give these people more attention than they deserve, but it's a reminder that we live in a dark world, where people judge one another, and say the most hurtful, cruel things," Amber wrote. "Please think before you type or speak your opinions," Amber continued. "The Bible tells us that the tongue is a fire — James 3:6 The tongue is also a fire,(A) a world of evil among the parts of the body. It corrupts the whole body,(B) sets the whole course of one's life on fire, and itself set on fire by hell." "Choose to be the light," she wrote in another post. "And know who you are in Jesus Christ so when flaming darts come are way you are wearing the armor of God. Not today Satan."
