From High School Sweethearts to Three Kids: Inside Lindsay Arnold and Sam Cusick's 16-Year Love Story

Some couples meet, fall in love, and get married. Dancing With the Stars pro Lindsay Arnold and Sam Cusick did all that—except they’ve been doing it since high school, and they’re still going strong.

Their story reads like a genuine rom-com. Arnold and Cusick started dating as teenagers in Salt Lake City and stayed together for six years before Cusick popped the question during a vacation in Africa in December 2014. Less than a year later, in June 2015, they exchanged vows in a Church of Jesus Christ of Latter-day Saints ceremony back home in Utah. At the wedding, Arnold told Us Weekly she’d loved Sam since she was 16 years old and was thrilled to spend the rest of her life with him. Now, more than a decade into their marriage, they’re living that promise.

The pair have built a full life together—one that now includes three children. Their daughters Sage and June arrived in November 2020 and May 2023, respectively. Then, in June 2026, their baby boy was born, completing the family. What makes their timeline particularly sweet is how they’ve documented it all: pregnancy announcements, family vacations to Hawaii and Lake Powell, anniversary tributes, and yes, even playful TikTok videos about Cusick’s questionable bed-making skills (he still has her heart, despite the wrinkled quilts).

Arnold has been candid about what keeps their marriage ticking. In June 2022, on their seven-year anniversary, she reflected on the importance of friendship within marriage—something she’s emphasized repeatedly over the years. In April 2025, when fans noticed she wasn’t wearing her wedding ring, she quickly clarified that she and Cusick were upgrading her engagement ring to mark their upcoming 10-year anniversary, not calling it quits. The couple’s easy banter on social media, mixed with genuine appreciation for one another, suggests they’re the real deal.

Sixteen years together, a decade of marriage, three kids, and counting. Arnold and Cusick’s journey from high school romance to the life they’re building now proves that sometimes the person you fall for at 16 really can be your person forever.
