"You got to fight. For your right. To Paaaarty!"

While the Bestie Boys do it best, this has become Travis Kelce's trademark celebration for the Kansas City Chiefs. And while he isn't afraid to take the microphone and sing, everyone knows that Taylor Swift is the true musician in their relationship. 

So when it comes to music, Kelce is constantly learning from Swift and is enjoying his evolving taste in music thanks to her. 

"It's definitely been fun to experience her taste in music, for sure," Kelce told Entertainment Tonight. "She's so amazing at what she does. And to find that creativity to see where she likes to pull things from and just, really, how she listens to music is very eye-opening for me. It's been fun to hear her take on it."

But his favorite songs will come as no surprise to anyone. And he makes sure to listen any chance he can. 

So any guesses who that might be? 

…

Okay, we'll just tell you: Taylor Swift. (I know! Nobody saw this coming)

"That's my everyday playlist," Kelce said. "Not just my game day."

Kelce has proven that he knows all the words to his girlfriend's hits, and one video posted by some of his friends showed that. The Chiefs tight end was out on the golf course with friends and they tried to rattle him by playing Swift's song, 'Bad Blood.'

However, instead of getting in his head, it just motivated him and he ended up singing along while also pretending to play the air guitar. 

In the background, one friend said, "no, this backfired," while another said, "oh he likes it."

So one thing is clear: Kelce loves Swift's songs.
