Madeline Gaudreau, the widow of Matthew Gaudreau, gave birth to their son, she announced on Instagram on Sunday.

The birth of their son, Tripp, comes four months after Matthew Gaudreau and his brother, Johnny, of the NHL's Columbus Blue Jackets, were tragically killed after a vehicle hit them while they were riding their bikes in Oldmans Township, New Jersey, in August.

In December, the driver of the vehicle was charged by a grand jury with two counts of reckless vehicular homicide, two counts of aggravated manslaughter, tampering with physical evidence and leaving the scene of a fatal accident, per CNN's Jacob Lev.

Matthew was 29 and Johnny was 31.

"The National Hockey League family is shocked and saddened by the tragic passing of Columbus Blue Jackets forward Johnny Gaudreau and his brother Matthew," NHL Commissioner Gary Bettman said in a statement in August. "While Johnny's infectious spirit for the game and show-stopping skills on the ice earned him the nickname 'Johnny Hockey,' he was more than just a dazzling hockey player; he was a doting father and beloved husband, son, brother and teammate who endeared himself to every person fortunate enough to have crossed his path."

Matthew played professional hockey in the ECHL, spending four years with the Worcester Railers and one season with the Reading Royals. Johnny played 11 seasons in the NHL for the Calgary Flames and the Blue Jackets. He scored 743 points across his career, collecting a career-high 115 during the 2021-22 season.
