The late Johnny and Mattew Gaudreau's sister, Katie Gaudreau, is pregnant, gearing up to welcome her first child with husband, Devin Joyce. "Our favorite news to share," Katie, 25, captioned an Instagram video on Thursday, February 26. The black-and-white video showed Katie wrapping her arm around her husband's neck while holding a pair of baby Nike sneakers in one hand. She held a sonogram in her other hand. Joyce, who was wearing a hat in the clip, turned it around to face the camera. His cap read, "Dad," in big block letters. Katie was wearing a matching hat that read, Mom.
