Chip Gaines says his fifth child with wife Joanna Gaines will be a son. The 43-year-old television personality announced in a cute video Wednesday on Twitter that Joanna is pregnant with a baby boy. "Alright, alright.. if we're going to announce the gender of our #5th child. It might as well come from my new friend #Gage! Take it away my man. @tebowfoundation," he wrote. Chip re-tweeted a clip of himself interacting with a little boy Saturday at the Tim Tebow Foundation Celebrity Golf Classic. "We're just about to have another little baby," the star told the young fan. "I can't think of a 'D' name. So can you help me think of a 'D' name?" "It's a little boy and I need a 'D' name," he said. "So far all I can come up with is 'Dragon.' She's like, 'You're not calling that baby Dragon!'" Chip and Joanna already share 12-year-old son Drake, 11-year-old daughter Ella, 9-year-old son Duke and 7-year-old daughter Emmie. Joanna showed off her baby bump in a slideshow of photos from the charity golf weekend. "What an amazing weekend with the @timtebowfoundation," she wrote. "Thank you for giving hope and love to so many #ttfgolf2018." Chip and Joanna announced Joanna's pregnancy in January following news they will end their HGTV series, Fixer Upper, after Season 5. The show premiered its fifth and final season in November.
