TNT’s cameras caught Taylor Swift’s stunned four-word reaction to Travis Kelce before overtime started during Game 4 of the Stanley Cup Finals between the Florida Panthers and the Edmonton Oilers.

Swift attended the hockey championship series game in Sunrise alongside her NFL boyfriend on Thursday evening from a luxury suite.

Heading into the sudden-death period, Swift had an animated comment to her partner, feeling the nerves of the game.

‘My heart was like…’ Swift said to Kelce, as the 35-year-old imitated her heart beating rapidly.

Kelce appeared to agree with the ‘Anti-Hero’ singer as he put his head in his hands.

Kelce has a home in the area, where he and Swift have been spending time in between his offseason activities for the Chiefs.

It is a rare time in public for the couple, who have been staying low-key since February’s Super Bowl loss for Kansas City.

Yet, coverage from TNT has shown Swift and Kelce more than any average fan, as the duo hung out in a luxury suite.

Instead of plans publicized days in advance of the 14-time Grammy Award winner attending a sporting event, her and the Kansas City Chiefs star’s appearance in Sunrise, Florida for the NHL title-series contest was only apparent about an hour before puck drop.

The Oilers won the game, 5-4, over the Panthers on an overtime goal from Leon Draisaitl.

Edmonton overcame a 3-0 first-period deficit to lead by a goal. Florida scored the game-tying goal with 19 seconds left in regulation.

The effects of waiting for overtime made Swift’s heartbeat increase, as witnessed by TNT’s cameras.
