Chiefs superstar quarterback Patrick Mahomes said Kelce told him «at the last minute» that Swift was attending the game but also noted: «Some things with [Kelce], he says it and you don't know if it's true or not.» Mahomes admitted he was under «a little pressure» to throw a touchdown pass to Kelce, who hauled in a 3-yard TD in the third quarter.
