If you’ve spent even five minutes scrolling through NFL Twitter or watching the Kelce documentary on Amazon, you already know that the Kelce family is basically American royalty at this point. But while Donna Kelce is out here crushing it in Hallmark movies and appearing on The Traitors, there’s another matriarch in the mix who stays a bit more under the radar. I’m talking about Kylie Kelce mom, the woman who raised the blunt, field-hockey-loving, "Princess Ky" herself.
Her name is Lisa McDevitt (though Kylie affectionately calls her "Lil Lis"), and honestly, she’s a vibe.
Most people assume Kylie just naturally became this confident, no-nonsense Philadelphia icon the moment she met Jason Kelce on Tinder. But that kind of personality doesn't just appear out of nowhere. It was forged in the suburbs of the Main Line, specifically in Narberth, by a mother who apparently has some of the most hilariously practical parenting advice you’ve ever heard.
Who is Lisa McDevitt?
Lisa isn't your typical "NFL mother-in-law" trying to grab a headline. She’s a Delco-adjacent legend in her own right. Along with Kylie’s dad, Ed McDevitt—who stands at a massive 6'9"—Lisa raised Kylie in a household where sports and honesty were the two main languages spoken.
Growing up in Narberth, Kylie was a self-described tomboy. She was the "stand-in son" for her dad, watching Eagles games every Sunday. But Lisa was the one in the background, keeping things grounded. While the world sees Kylie as this pillar of strength for Jason, Kylie sees Lisa as her own blueprint.
The "Test Drive" Conversation Everyone is Talking About
We actually got a rare, deep look into their relationship recently on Kylie’s podcast, Not Gonna Lie. Kylie dropped a bombshell about a conversation she had with her mom back when she was younger.

Get this: A teenage Kylie once told her mom she was thinking about "saving herself for marriage."
Now, most moms might give a proud nod or a lecture on values. Not Lil Lis. She looked at Kylie and basically told her she’d probably change her mind. Her actual quote? "You gotta test drive a car before you buy it." It’s that kind of blunt, Philadelphia-area realism that explains exactly why Kylie is the way she is. She doesn't sugarcoat things. She doesn't do "fake." That transparency clearly came straight from Lisa. Kylie has credited that specific moment with keeping their relationship "open and honest" as she navigated the dating world—eventually leading her to a certain bearded center for the Eagles.
Raising a "Queen of Philly" in the Main Line
Kylie Kelce mom didn't just raise a celebrity; she raised an athlete. Lisa and Ed were staples on the sidelines when Kylie was playing field hockey for Lower Merion High School and later at Cabrini University.
If you want to understand the McDevitt family dynamic, you have to look at the height. Kylie is 5'11", which she used to be super insecure about. In school, kids were mean. They called her "huge" or told her she "looked like a man."
Lisa was the one who helped her navigate that. Imagine being a teenage girl struggling with your height when your dad is nearly seven feet tall. Lisa helped Kylie "switch the narrative," encouraging her to own her stature. By the time Kylie met Jason and his massive offensive linemen friends, she finally felt "normal sized," but the confidence to get to that point started at home with Lisa.

The Relationship Today: Grandkids and Chaos
Fast forward to 2026, and Lisa is now a grandmother to four girls: Wyatt, Elliotte, Bennett, and the newest addition, Finnley.
If you’ve seen the "lived-in" glimpses of the Kelce mansion on social media—toys everywhere, kids scooting on their butts, total beautiful mayhem—you’re seeing the result of Lisa’s parenting style. Kylie admits she looks to her mom as a total role model for how to handle the chaos.
Lisa is still very much a part of their daily lives. When Jason was playing, and even now in his retirement/broadcasting era, the McDevitt parents are the ones providing the local support system. While Donna Kelce is often flying between Kansas City and wherever else the spotlight hits, Lisa is the "boots on the ground" grandma in Pennsylvania.
What Most People Get Wrong
People often try to compare Kylie Kelce mom to Donna Kelce, looking for some kind of "Mother-in-Law Wars" drama. Honestly? It’s not there.
Kylie has been very vocal about how "warm and inviting" the Kelce family was when she joined, but she’s also made it clear that her own family is "tight-knit" and small. Lisa McDevitt doesn't seem to have any interest in being a "momager" or a reality star. She’s the lady in the stands, the one giving the "test drive" advice, and the person Kylie calls when the four kids are driving her up a wall.

Lessons from the McDevitt Playbook
If we can take anything away from the way Lisa raised Kylie, it’s these three things:
- Honesty over Optics: Don't tell your kids what you think they want to hear. Tell them the truth, even if it’s about "test driving cars."
- Support the Passion: Whether it was field hockey or Kylie’s dream of becoming a veterinarian (which she still talks about!), Lisa stayed in the corner.
- Stay Local, Stay Real: Despite the $6 million mansion and the Super Bowl rings, the McDevitt influence is why Kylie still feels like the girl next door from Narberth.
If you’re looking to channel some of that "Lil Lis" energy in your own life, start by being a little more honest with the people you love. You might find that it builds a foundation of trust that lasts way longer than any 15 minutes of fame.
Keep an eye on Kylie’s podcast for more "Lil Lis" cameos—they’re usually the highlight of the show.
