Travis Kelce may have lost to the Buffalo Bills Sunday ... but he's still a big winner in the eyes of his superstar girlfriend, Taylor Swift, who planted a passionate kiss on his cheek at the game!!!
Check out this photo ... Taylor closes her eyes as she holds Travis' head with both hands and delivers some major lip service to the side of his grinning face. Travis is one lucky guy, indeed!!!
The happy couple was snapped at a festive Christmas-themed bar for a postgame party after the K.
