"16 years and it feels like we're just getting started... I love you Chip Carter Gaines," Joanna, 41, captioned alongside a PDA-filled photo of them..
Chip, 44, and Joanna have experienced quite a lot on their marriage journey.
They've been busy in the parenting department by having not one, not two, not three, not four, but five kids!
Joanna gave birth to baby number five, a boy named Crew, in June of 2018.
Things haven't always been the easiest for them, especially being in the public eye.
Joanna talked about her insecurities when it comes to the pressures of social media in a column for Magnolia Journal earlier this year.
