Jason Kelce said he's seen a major change in his brother Travis Kelce since 'people,' such as his girlfriend Taylor Swift, have come into the tight end's life.

Kelce and Swift have been together since Sept 2023, when she made her first appearance at Arrowhead Stadium against the Chicago Bears. Since then, she has appeared at 23 total Chiefs games, including two Super Bowls. And Jason Kelce, Travis Kelce's older brother, has noticed a major change from the tight end amid his relationship.
