Jason Kelce celebrated his little brother's engagement to Taylor Swift in the most Jason Kelce way possible -- by screaming and dropping a big ol' F-bomb!!!
The Philadelphia Eagles legend took to the "New Heights" Instagram page just before Wednesday's episode dropped to celebrate Travis' big day ... and he didn't hold back.
He at first explained to his fans that the latest episode of the brothers' show wouldn't touch on the engagement because they filmed it on Monday .
