She is the first mother to have two kids competing in the Super Bowl: Jason Kelce, who tosses the ball to Eagles quarterback Jalen Hurts, and Travis Kelce, who catches passes from Chiefs quarterback Patrick Mahomes.

“It’s going to be tough, but I’m just gonna cheer my head off when the offense is on the field,” Donna Kelce told The Post. “So I’ll be shouting the entire game. I’m rooting for both of them to score. A lot.”

She has seen each of them win a Super Bowl, but at the end of the night, she will be bittersweet since only one of them will have a second ring.

“Somebody’s gonna go home a loser for sure, and one of ’em’s gonna be heartbroken because they didn’t beat their brother,” she said. “That’s what it’s gonna come down to, it’s gonna come down to bragging rights.”

It was a bragging rights childhood for the Kelce family in Cleveland Heights, Ohio.

“It was always a competition,” Donna explained. “Who gets to the table first?” Who has the final chicken wing? Who will sit in the front seat of the car? Who will take the elevator to the bottom floor first? It was always a competition. They don’t enjoy losing. They want to win, and that is just who they are.

“You hate each other when you’re growing up, but later on in life, you’re best buds, because you’ve gone through everything together, so it’s kinda fun,” she remarked.

Kelce versus Kelce would be devastating for both.

“They competed with the city’s best. “It was living right next to them,” she explained. “In the next room.” Whether it was mini-hockey in the basement or whatever, there was always competition.”

Football was not their first love, but of course they supported the Browns.

“It’s just surreal,” Donna explained. “It’s like you’re in a dream, and you’re not sure if it’s real. We’ve considered playing them for the previous ten years that Travis has been in the league, but they normally only play every four years, so the only time they’d ever meet would be in the Super Bowl, but sometimes throughout the season. I know they’ve been discussing it since they were ten.

“But the assumption was always that they were on the same team, and they were playing for the Brownies. So they both had Bernie Kosar jerseys, pants, and helmets.

“They both had a hockey dream,” she explained. “That is what they wanted to play. They skated throughout the majority of their lives, beginning when they were three years old. They enjoyed watching football but were unable to play until middle school.I recall Travis approaching me one year and saying, “I want to go to Canada and play in the junior leagues.” And I’m thinking, ‘There’s no way I’m letting anyone else raise my child. He was good enough to play anywhere; he was extremely good. However, it appears that you spend the most of the year away from your family. It simply wasn’t an option.

Football was not initially a possibility because Mom refused to allow it.

“I wouldn’t let them do that,” she replied. “No one ever claims, ‘I was the best peewee football player ever.'” And it’s not very well arranged. So there’s always suspicion of parents, injuries, and so on. They aren’t trained coaches, so I had them wait until middle school to play football. They played seventh and eighth grade.”

They did not play football together until they attended the University of Cincinnati in 2009. They didn’t play together in high school when Jason was a senior and Travis, the quarterback at the time, was a sophomore since Travis missed the season.

“Because he failed French. And I wouldn’t take him to summer school,” Donna explained. “I said, ‘No buddy, you screwed up, you must pay for this.'” So he did not play with him.”

Following the Eagles’ NFC Championship victory, general manager Howie Roseman (center) stands with defensive end Brandon Graham (55), offensive tackle Lane Johnson (65), defensive tackle Fletcher Cox, and center Jason Kelce (62).

The boys played lacrosse in middle school, and Jason did so in high school.

“Travis was very good as a pitcher, so he did that,” she told me. “Jason played hockey all through high school and Travis switched from hockey to basketball when he became a freshman in high school.”

Jason’s schoolboy enthusiasm as a linebacker and then as the Eagles center began with hockey when he was 10 or 11.

“I remember the first time that Jason played hockey,” Donna said, “when you’re a squirt and you can actually start checking people, he just skated up to me with this beaming grin on his face and said, ‘Mom. “I’ve finally discovered what I’m really, really good at!”

She described Jason as having “many layers.” He is a highly enthusiastic person, and he does not work well with those who do not strive hard. So he really came into his own when he got to the pros, when everyone is working hard to be the best they can be. He dislikes slackers, plain and simple. He never dealt with it properly. Jason spent a lot of time in the penalty box while playing hockey because he was working so hard and was so passionate about playing and winning. This also applies to lacrosse. He was always the most heavily penalized guy.”

She described Travis as someone who simply enjoys life. He enjoys everything about being outside, being with people, and doing activities. He’s incredibly driven, similar to Jason, but more than anything, he values his friends and family, as well as the friends he’s gained and kept throughout the years. He has assisted others in a variety of ways throughout the years, whether their bike was stolen or not; he’s a community guy.”

Similar, but distinct.

“You know they’re very very similar, both high-energy, both funny,” she went on to say. “Jason is pensive and calculated. And Travis is more present. So that’s how they vary, really. Both enjoy socializing. “There’s not much of a difference.”

Donna, her brother, and her ex-husband Ed attended the NFC Championship game at Lincoln Financial Field before meeting up at Chickie and Pete’s to see the Chiefs defeat the Bengals – Ed fled in the fourth quarter and walked 20 minutes to the bar, while Donna and her brother were escorted by police.

“I have a jersey where each shoulder is different,” she went on to explain. “One is an Eagle, while the other is a Chief. And I’ve got an Eagles jersey on the back and a Chiefs jersey on the front with their numbers. There’s a 62 on the rear and an 87 up front. Travis had it custom-made.”

She will arrive in Arizona on Monday and plan to wear it to the Kelce Bowl.
