'DWTS' alum Lindsay Arnold welcomes 3rd baby with husband Sam Cusick

Lindsay Arnold’s newest little one has arrived. The "Dancing With the Stars" alum welcomed baby No. 3 with her husband, Sam Cusick, she announced Thursday. "Baby boy is here and we are so grateful and so in love 🥹💙," she wrote on Instagram. She added a hashtag noting their son arrived via a cesarean section; the couple has not yet shared his name.

Arnold and Cusick, both 32, are already parents to daughters Sage (born November 2020) and June (born May 2023). The family included the girls in a maternity shoot when Arnold announced the pregnancy in November 2025, and used balloons filled with blue confetti the following month to reveal they were "bringing [their] first boy into this world." Arnold later wrote that she and Cusick opened the results privately but recalled Sam's excited "YESS!!!!!!" when she read "boy." The couple have been together since they were 15, got engaged in December 2014 while vacationing in Africa, and married in Utah the next summer.
