Chip Gaines Runs Charity Marathon with Son Crew, 3: 'My Baby Is Better Than Your Baby' In March, Joanna posted a heartwarming video to Instagram documenting Crew's evening ritual of saying goodnight to all of his plants in their greenhouse. In the clip, little Crew walks up to each individual plant to wish them goodnight and tell them not to "let the bugs bite." "Before the sun sets, he tells his little plants good night and to not let the (bed) bugs bite! 🌱✨🌙," Joanna, who shares son Crew with husband Chip, captioned the clip. In June, Joanna shared a photo herself and Chip to celebrate their 19th wedding anniversary. In the sweet picture, they're cozying up in a shiny black dining booth. "19 years ❤️," Joanna captioned the Instagram post. To close out the special sentiment, she added a hashtag that says, "I like you a lot." Earlier this year, the Magnolia Network stars announced a new dream project — their new show, Fixer Upper: Welcome Home - The Castle. In the eight-episode limited series, debuting in September, they'll be renovating a 100-year-old Waco castle they've been trying to buy for 20 years — even longer than their years of marriage!
