Celtics' Tatum angers Boston fans by celebrating Blues' Stanley Cup win

Jayson Tatum was thrilled to see his hometown St. Louis Blues capture their first Stanley Cup in franchise history Wednesday night.

Moments after the Blues' Game 7 victory, the Boston Celtics forward took to Twitter to join fellow St. Louis native and Washington Wizards guard Bradley Beal in celebrating the historic moment.

Tatum's tweet didn't go over well with some Celtics fans, though, as the Blues defeated the Boston Bruins to win the Cup.

Tatum did receive plenty of congratulatory messages as well and later clarified on Instagram that he still has plenty of love for the city of Boston and the Bruins.
