People Editorial Guidelines Published on March 7, 2018 01:11PM EST Share Tweet Pin Email Chip and Joanna Gaines are seeing blue! The Fixer Upper couple are going to add a son to their household, Chip announced on Twitter Wednesday alongside a sweet clip featuring a little boy named Gage, taken over the weekend during their attendance at a golf event for the Tim Tebow Foundation. In the adorable video, Chip jokes in his explanation to Gage that he and his wife are about to have another baby — their fifth child — because “Uncle Chip has lost his mind.” “I can’t think of a D-name. Can you help me think of a D-name?” he asks Gage, who replies, “A boy?” — a great guess, considering the couple’s sons Duke, 9, and Drake, 12. “A boy! Is that a secret? I don’t know — that might not even be allowed on Twitter,” Chip jokes, telling Gage, “You better keep that to yourself, dude!” Want all the latest pregnancy and birth announcements, plus celebrity mom blogs?
