Johnny and Matthew Gaudreau's Sister Katie Gives Birth to Her 1st Baby

Katie Gaudreau- the sister of late hockey stars Johnny and Matthew Gaudreau - has welcomed her first baby with husband Devin Joyce.

The baby boy is named Matthew, an apparent tribute to her older brother.

"He's here. 💙," Katie, 27, announced via Instagram on Tuesday, June 23, alongside a carousel of the newborn. "Matthew Guy Joyce. June 20, 2026 • 9:00 AM • 7lb 10oz • 20inches. The moment our hearts grew bigger than we ever imagined. Welcome to the world, sweet boy. 🤍."

Katie announced her pregnancy in February, gushing via Instagram at the time, "Our favorite news to share."

In the accompanying black-and-white video, Katie held a pair of Nike baby sneakers and ultrasound photos as she embraced Joyce, 28. The parents-to-be also showed off their matching "mom" and "dad" hats.

In March, Katie offered an update on her "little miracle" as she hit the 22-week mark.

"This pregnancy hasn't looked the way I imagined it would," she captioned black-and-white Instagram photos of her baby bump. "It hasn't been all sunshine and excitement. There's been a lot of uncertainty. A lot of fear. It's been a pregnancy that's closely monitored and carefully watched, and we've been surrounded by so much support. And I'm so proud of this little life."

After her brothers' deaths, Katie paid tribute to Johnny and Matthew in a touching Instagram post.

"To know these two was to love these two," she wrote in September 2024. "There are absolutely no words I have to express the bond my family shared. The entire world knows there would never have been a John without Matty or Matty without John. The absolute best big brothers a little girl could have asked for. This will never be a goodbye post because I will never stop saying your names and honoring you both."

Katie concluded by vowing to "take the best care of" their parents, sister Kristen, Johnny's wife, Meredith, Matthew's wife, Madeline, and her brothers' kids.

Both Meredith and Madeline were pregnant when their husbands died. Madeline gave birth to her and Matthew's first baby, son Tripp, in December 2024. Less than four months later, Meredith welcomed her and Johnny's son Carter in April 2025, with the couple's third child joining their daughter, Noa, and son Johnny.
