John Krasinski Teases Jenna Fischer by Attending Stanley Cup Final with 'The Office' 's Roy

John Krasinski teased his The Office co-star Jenna Fischer while at Wednesday night's Stanley Cup Finals game between the Boston Bruins and the St. Louis Blues

Before Jenna Fischer’s team was ultimately victorious during the Stanley Cup Finals Game 7 on Wednesday, her former onscreen husband snuck in one last dig.

The St. Louis Blues defeated the Boston Bruins, besting 250-1 odds to win the championship. John Krasinski, who portrayed Jim Halpert — Fischer’s character Pam’s onscreen husband in The Office — has engaged in a back-and-forth rivalry with the star, as he’s a Bruins fan and she roots for her native Blues.

The trash talk continued on Wednesday, with Krasinski tweeting a video from the TD Garden in Boston at Fischer.

In the clip, Krasinski said, “Jenna Fischer, I know we’ve been having our ups and downs recently.”

He continued, “I just wanted to say, I’m really sorry you’re not here. This is your seat right here, and I was really bummed that you couldn’t make it. But listen, honestly? Let’s just have the best team win.”

While talking, Krasinski’s actual seatmate returned — David Denman, the actor who portrayed Pam’s ex-fiancé Roy on the beloved series.

Fischer, 45, quipped back shortly after Krasinski posted the clip, referencing Jim, Pam, and Roy’s love triangle backstory and warning her Office co-star, “Ha. Ha. Ha. Well played. Just be careful he doesn’t leave you at the game. #GoBlues.”

Unfortunately for Fischer, Krasinski and Denman aren’t the only Bruins fans on The Office cast, with fellow Massachusetts-native Steve Carell showing his support on Twitter while sporting a Bruins hat.

The photo prompted Fisher to reply, “Steve!!! Not you too!! #LetsGoBlues #Gloria.”

The Office ended after nine seasons in 2013, winning a handful of Primetime Emmy Awards and Golden Globes over the years.
