Everybody loves Kylie Kelce!

In this week’s cover story on Kansas City Chiefs tight end Travis Kelce and his brother, Philadelphia Eagles center Jason Kelce, a source explains to PEOPLE why Jason’s wife, Kylie, fits in so well with the Kelce family.

“Kylie is so great. She’s very sweet and level-headed, very cool,” says the insider. “Everybody loves her, like everybody.”

According to the source, Kylie, 31, is “one of those people where you meet her, and immediately you’re like, you’re amazing.” Despite her hectic schedule from being a mother-of-three and married to a busy NFL star, Kylie “goes with the flow.”

She and Jason, 36, are “great partners,” the insider adds.

Kylie and Jason wed in Philadelphia in April 2018 and welcomed their first child, daughter Wyatt Elizabeth, 3, on Oct. 2, 2019. Their second daughter, Elliotte Ray, followed on March 4, 2021. The couple’s third daughter, Bennett Llewellyn, was born on Feb. 23, 2023.

Kylie has become a fan-favorite member of the Kelce family as their celebrity reaches new heights.

On a recent bonus episode of New Heights with Jason and Travis Kelce, Kylie asked her brother-in-law to help convince Jason to get a cat. “No, here’s the deal, I told Jason that I want to get a cat,” Kylie said on the episode.

“And he told me no. And I feel like you might like cats now,” she added, poking fun at Swift’s possible influence on Travis as a proud cat mom.

The singer-songwriter’s pet family includes three felines — Meredith Grey, Olivia Benson, and Benjamin Button — whom she openly adores.

Prior to their love story, Kylie and Jason first interacted on the dating app Tinder, where Kylie thought Jason was a catfish initially.

In the Amazon Prime documentary Kelce, Kylie said she didn’t even know the person she matched with on the app was an athlete when she first connected with Jason. “None of his pictures showed Eagles football,” she explained.

When Kylie and her friends noticed that Jason looked “kind of familiar” from his profile, they looked him up on a Google image search. She put a name to the face and assumed, “It can’t be him; it’s a catfish.”

When Jason invited Kylie to meet him and some friends at a local bar, she thought it would be “hilarious either way” if it turned out to really be the Eagles player or someone “pretending to be him,” she said.

Kylie went to the bar to meet Jason and his friends for a drink, and the NFL player has a vivid memory of their first meeting. “Right away when she walks in the door, the most beautiful woman I’ve ever seen,” Jason recalled.

The Eagles center said it was “very much like love at first sight” when he and Kylie met that night.
