Baby No. 4 has arrived for Justin Moore and his wife Kate -- and it's a boy! A representative for the country star confirmed the news to People on Monday (June 12).

Thomas South Moore was born on Sunday (June 11) at 3:33PM in Little Rock, Ark. He weighed 7 pounds, 14 ounces at birth and measured 20 inches long. Moore's first son shares his first name with the singer's late grandfather; his family will call him by his middle name.

“Kate and I already felt like the most blessed people in the world with our three beautiful daughters, but we feel even more blessed to have a healthy baby boy now to add to our family,” Moore says. “God has given us another wonderful gift."

Moore and his wife were already parents to three girls: 7-year-old Ella Kole, 5-year-old Kennedy Faye and 2-year-old Rebecca Klein. Thomas South's older sisters, his parents say, "are already obsessed with him."

Moore and Kate announced that they were expecting their fourth child in late January. They waited until Thomas South was born to find out his sex.

Moore won't have too much time to spend at home with his newly expanded family just yet: He's got concerts scheduled on both Thursday (June 15) and Friday (June 16) this weekend. Thursday's stop is at Country Jam in Grand Junction, Colo.
