The couple got engaged in October 2015 after dating for four years.
Similar to Lindsay Arnold and her husband Samuel Cusick, Witney and Carson were high school sweethearts.
Fellow Dancing with the Stars dancers Brittany Cherry, Jenna Johnson, and Emma Slater were among Witney's bridesmaids, with Lindsay Arnold also serving as her matron of honor.
In January 2021, Witney gave birth to the couple's first child, a baby boy.
"After a really hard 24 hour labor, and an unexpected c-section... we are all healthy and well," Witney captioned a black-and-white photo of her family's hands intertwined on Instagram.
"We are so grateful & we've been soaking up every moment with our perfect angel boy. Thank you for all the prayers!"
