Jason Kelce’s little girls got all fired up thanks to a fun gift from Grandpa.

On the latest episode of the newly retired NFL star’s New Heights podcast with brother Travis Kelce, the two talked about another special family gathering that took place before the beloved Philadelphia Eagles center’s big announcement.

The family gathered to celebrate Jason’s daughter Elliotte’s third birthday, with the 34-year-old Kansas City Chiefs tight end recalling a funny scene he watched unfold between the birthday girl and big sister Wyatt, 4.

“One of Ellie’s birthday gifts was airplane guns. It was foam airplanes that you put on top of a gun and you shoot it,” Travis explained.

“When I tell you, the girls were going nuts,” he laughed, telling Jason, “It started off with Grandpa and Dad in the yard saying, ‘Hey, if you guys can hit me, you get like a popsicle’ or something.'”

Both girls were firing at Ed Kelce until, satisfied with their reaction, he rejoined some of the adults inside.

“But then it turns into whoever’s in the yard is the target, right? Little Elliotte, on her birthday, runs down there to go retrieve her planes to come back and do it again, and sure enough Wyatt was locked and loaded.”

In his attempts to be a good influence, Travis told his oldest niece, “Wyatt, don’t hit your sister; be careful.”

“And as I’m saying it, she keeps tracking, keeps tracking, and finally stops,” he said, mimicking Wyatt’s aim. “Boom. Right to the side of the head.”

Both brothers laughed as Jason admitted, “I didn’t know it was a headshot.”

Travis told Wyatt she shouldn’t have done that, but she did a “slow turn” with a “smile” that let the uncle know there was “pure joy in going straight to the dome” with her shot.

“The girl’s got it,” he said of Wyatt.

“Yeah, she’s got it. And Ellie’s tough,” Jason added.

“Yeah, Ellie was having a blast,” Travis laughed.

In addition to Wyatt and Elliotte, Jason, 36, and wife Kylie Kelce are also parents to daughter Bennett, 12 months.

In a New Heights episode airing last month, the father of three laughed as he revealed his youngest mastered the art of yelling.

“Bennie is in a stage right now where she has found that she can yell, so she’ll just be sitting there — this is why I think we may be part Viking. And now Wyatt’s giving a response yell because she’s tired of Bennie yelling at her.”

“It’s awesome,” the uncle snickered as the two sisters continued their back and forth.
