'DWTS' Pro Lindsay Arnold Welcomes Baby No. 3
Lindsay Arnold is officially a mother of three!
The Dancing With the Stars pro, 32, took to Instagram on Thursday, June 11, to announce that she and her husband, Sam Cusick, had welcomed their third baby, a little boy.
After undergoing a planned C-section, the professional dancer shared some of the first photos of her little boy cuddled up on her chest at the hospital as Cusick, 32, proudly looked on. In another photo, the father of three can be seen cradling his son while taking in some of his first moments with the little one.
"Baby boy is here and we are so grateful and so in love," Arnold wrote in the caption of her Instagram post, adding the hashtags "#babyboy," "#birth," and "#csection."
Arnold's news was met with plenty of well-wishes from her Dancing With the Stars family, with fellow pro Emma Slater commenting, "He's here!!!! CONGRATULATIONS you guys!! So happy for you!" Daniella Karagach chimed in, "Love you!!!! Congrats you guys," as Jenna Johnson wrote alongside several gushing emojis, "Omggggg!!!! Baby boy!"
Arnold and Cusick, who tied the knot in June 2015, also share daughters Sage and June, whom they welcomed in November 2020 and May 2023, respectively.
The couple announced in November 2025 that they were expecting a third child, with Arnold writing on Instagram at the time, "BABY CUSICK #3 IS ON THE WAY ... We could not feel more blessed, grateful and excited. We love you so much already baby and we can't wait to meet you!!"
The following month, Arnold revealed that she and Cusick were expecting a son, adding their first boy to the bunch.
"We feel so beyond grateful and blessed to be bringing our first boy into this world," the ABC dance competition show alum wrote on Instagram in December 2025. "Our girls cannot wait and ask every day how much longer until baby brother is here."
