Celebrity Twitter feuds: They’re the cure for regular Twitter feuds. Following in the footsteps of such faux-beefs as Hugh Jackman vs. Ryan Reynolds, two former on-screen lovebirds from one of Netflix’s most popular programs are duking it out over the great sport of hockey. We’re of course speaking of the one-time The Office alumni Jim Halpert and Pam Beesly, i.e., John Krasinski and Jenna Fischer, reunited over their love for different teams competing for this year’s Stanley Cup.

This year it’s come down to the Boston Bruins and the St. Louis Blues. Krasinski, a Massachusetts boy, is pro-Bruins; Fischer, a native of St. Louis, is for the Blues. As caught by Entertainment Weekly, it all started when Fischer lent her notoriety and unbridled enthusiasm to the Blues’ official Twitter account.
