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

Lindsay Arnold’s 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 in the Instagram post’s caption, noting with a hashtag that their son, whose name they have yet to share, arrived via a cesarean section, or C-section.

The couple is also the parents of daughters Sage and June, born in November 2020 and May 2023, respectively.

Arnold and Cusick, both 32, included the girls in the maternity shoot announcing their expanding family in November 2025.

“We could not feel more blessed, grateful, and excited🫶🏻,” the dancer told her followers at the time. “we love you so much already baby and we can’t wait to meet you!! 🥹”

She used balloons filled with blue confetti to reveal they were “bringing [their] first boy into this world” the following month.

“We opened our results together and in private but I wish y’all could have heard/seen Sam’s excited ‘YESS!!!!!!’ when I read boy to him 😭,” Arnold wrote in December 2025.

“He is the best girl dad and I just know he is going to be the most amazing boy dad, our son is so lucky 🩵,” she gushed.

Arnold, who continued to share bump updates in subsequent months, has been with her partner since they were 15.

The high school sweethearts got engaged in December 2014 while vacationing in Africa.

They tied the knot in Utah the next summer.

While Arnold was on “DWTS” at the time, she quit the ABC show in August 2022 after more than a decade as a pro to focus on her family.

She shared the decision in a lengthy Instagram caption at the time, calling it “one of the hardest decisions” of her life.

However, Arnold clarified, “I feel so much peace about it and know that it is the right thing to do.

“It’s so important to me that you understand none of this has anything to do with my love for the show as that will NEVER change,” Arnold added.
