4:10 PM PT -- Travis Kelce and the Chief appear well on their way to a full-blown routing of the Chicago Bears -- an ass-whooping that Taylor Swift looked ecstatic to take in with a great view.
Check out these photos, obtained by TMZ, that show TayTay enjoying herself in the private box at Arrowhead Stadium alongside Travis' mom ... not to mention of a bunch of pals she had around who were watching the game with her.
As you can tell, TS is having a blast ... and if this jubilance is suggestive of how things are going between her and TK -- that's a really good sign.
