Although Kansas City Chiefs tight end Travis Kelce has been a public sports figure for years, he was thrust into an even greater level of fame when he started dating Taylor Swift.

And thanks to Kelce’s podcast, New Heights, folks are getting to know his brother, Philadelphia Eagles center Jason Kelce, and sister-in-law, Kylie Kelce, too.

So what is Travis and Kylie’s relationship like, anyway? Do they get along? Based on their interactions on the podcast and in Travis’ reality dating show, Catching Kelce, the siblings-in-law seem genuinely like each other—even if they do get in plenty of jabs.

On the Nov. 1 episode of New Heights, Travis shared what he thinks of Kylie in a bonus scene at the very end.

“Trick or treat, smell my feet, give me something good to eat,” Travis sang after the doorbell rang at Jason’s house.

When Kylie asked Jason to pass her a bag of candy to give to trick-or-treaters, Jason did not do so quickly—and even then, he attempted to give her Nerds Gummy Clusters, which aren’t individually wrapped.

For the record, Kylie also thinks Travis is pretty great—especially when it comes to his role as an uncle to her three daughters, Wyatt, Elliotte and Bennett.

He is like the absolute best uncle you can imagine,” Kylie told People in February.

“I tell everybody, he comes to our house to visit and the poor guy doesn’t sit on the couch because our daughters will be like, ‘No, no, you sit on the floor. We’re gonna do a puzzle. We’re gonna build blocks. We’re gonna do this, we’re gonna do that.’”

Although Kylie said she’s told Travis he can tell her kids no, he’s not so sure.
