Lindsay Arnold and her husband, Sam Cusick, will soon be outnumbered.
The Dancing With the Stars alum announced on Monday, November 24, that she is pregnant with the couple’s third baby.
“BABY CUSICK #3 IS ON THE WAY✨✨ We could not feel more blessed, grateful, and excited🫶🏻,” Arnold, 31, wrote via Instagram. “We love you so much already baby and we can’t wait to meet you!! 🥹 #pregnancy #babyontheway.”
The professional dancer shared a series of family photos featuring a sonogram of their third baby. The couples’ two daughters, Sage, 5, and June, 2, were also photographed holding the sonogram.

Arnold and Cusick — who tied the knot in June 2015 — previously welcomed daughters Sage in November 2020 and June in May 2023.
One year after becoming a family of four, Arnold believed she could be pregnant with her third baby despite having an IUD.
“As far as life and updates with me, fun fact, I took a pregnancy test yesterday because I thought I was pregnant,” she said in an August 2024 TikTok video, noting that she and Cusick were “not trying” for another baby yet and there was “no reason” she should be expecting.

“I was super nauseous for three days in a row. My period has been so weird and all over the place,” she explained. “I thought I was [pregnant], but I wasn’t. So that was a kind of a little rush of like, ‘OK, OK, not pregnant.’ So there’s that.”
Arnold shared that she’d been “asked a lot more frequently” as of late when she and Cusick planned to have another baby.
“June is now at the age where it wouldn’t be that crazy for me to get pregnant right now,” she said. “But we definitely aren’t quite ready yet.”
Arnold elaborated that her daughters’ age gap of two and a half years was ideal, adding that she didn’t want to have kids “any closer than that.”
“So that would mean us starting to try maybe [at the] end of the year, like December [or] January,” she told her followers. “Only thing that’s so hard is it took me, like, 11 months to get pregnant with June. Part of me is like, ‘Do we start trying in case it takes a long time?’ But then I’m like, I feel like when you do that then you get pregnant on the first try.”
Regardless of their timeline, Arnold knew she wanted to expand her and Cusick’s family.

“I can’t even tell you how many times I go to leave the house and go, ‘Oh, we forgot,’ and feel like I forgot a child,” she said. “Or when I look at a family photo, I’m like, ‘Wait, where?’ And then I realize, I’m like, ‘No, that’s all of our kids.’”
One year later, Arnold hinted at her readiness for baby No. 3 in an August 2025 TikTok video.
“Me to my husband: ‘Maybe we should start trying to get pregnant this month,’” she wrote at the time. “My IUD still in my body: … ”
Arnold included Taylor Swift’s song “I Forgot That You Existed” with the video, lip-syncing to the lyrics, “I forgot that you existed / And I thought that it would kill me, but it didn’t.”
In her caption, she teased, “Maybe next year?”
However, the following month, Arnold revealed in another TikTok video that she and Cusick were “officially trying for baby No. 3.”
