NFL star Travis Kelce shared a glimpse into his relationship with Taylor Swift, as he used his nickname for the pop icon on his podcast Wednesday.

Travis' brother, Jason Kelce, pointed out that Swift had liked an Instagram post on the Kansas City Chiefs' page about the football player being the fastest tight end to reach 11,000 receiving yards during Wednesday's episode of "New Heights."

"Thanks, Tay," Travis said during the podcast, which is hosted by the brothers. "I appreciate you on the Chiefs page supporting."

"Has she always been a fan of tight end receiving yards?" Jason jokingly asked.

Travis explained he had "a little bit of a clue" that she might do something crazy.
