Travis Kelce and Taylor Swift are going strong. As the pop superstar, 34, continues to support the Kansas City Chiefs tight end, also 34, at his games, a source tells PEOPLE exclusively the couple remain “really happy” together.

Speaking for the first time about their romance to Time in December, Swift similarly underscored their support for each another. “When you say a relationship is public, that means I’m going to see him do what he loves, we’re showing up for each other, other people are there and we don’t care,” said the Grammy winner. “The opposite of that is you have to go to the extreme amount of effort to make sure no one knows that you’re seeing someone. We’re just proud of each other.”

Swift is currently on a break from her record-breaking Eras Tour and is set to return to the stage next month. In November Kelce flew to Buenos Aires during his bye week to cheer on his girlfriend at her show, where he was seen singing and dancing along to every song. After the show, the couple delighted fans when Swift ran into his arms for a romantic kiss after changing the lyrics to her song “Karma,” giving Kelce a shoutout: “Karma is the guy on the Chiefs coming straight home to me.”
