Kansas City Chiefs All-Pro tight end Travis Kelce is reportedly "focusing on football like he always has" amid his new relationship with pop superstar Taylor Swift, an insider with knowledge on the situation told PEOPLE.com Monday (October 2) night.

"During the NFL season, his priority is the Chiefs, and it’s all about the team," the source said.

Kelce, 33, and Swift, 33, are reportedly "still just getting to know each other" and haven't yet defined their relationship, according to the source who added, "it's nothing too serious."

"He is a charming guy. It’s more of a hanging out situation than dating," the source said.

Swift attended the Chiefs' game for the second consecutive week amid her apparent growing relationship with Kelce. The singer was seen walking into the team's 'Sunday Night Football' game against the New York Jets at MetLife Stadium with actress Blake Lively among a group that also included actors Ryan Reynolds -- Lively's husband -- and Hugh Jackman and singer Sabrina Carpenter in a video shared by the Athletic's Dianna Russini, as well standing alongside Kelce's mother, Donna, and Brittany Mahomes, the wife of Chiefs quarterback Patrick Mahomes, during NBC's live broadcast.

Kelce broke his silence on his relationship with Swift during the latest episode of his New Heights podcast released on Wednesday (September 27).
