Neither side explained the reasons for the split -- though Kelce had said rumors of infidelity were simply not true.
But, get this ... Kayla was recently spotted at a Chiefs game (hanging out with Matthews again) -- sparking hope she and Travis were back on good terms.
AND IT'S TRUE -- not only did they make up, they're dating again! Travis made the status of their relationship crystal clear during his convo with Ogwumike calling her his "girlfriend" and promising to shower her with gifts for the holidays.
"She's the best," Kelce said about Kayla ... "She's the absolute best."
Kelce and Kayla are definitely fan favorites when it comes to celebrity couples -- remember when they raged together during the Super Bowl parade in K.C. back in February???
