There's been a shift in Jason Kelce since his retirement from the NFL , according to his wife Kylie Kelce . In fact, the former Philadelphia Eagles player is "more conscious about what he’s putting in his body," Kylie told E! News in an exclusive interview, "because he isn’t burning calories like he used to." And now that Jason is off the field, working as a commentator on ESPN's Monday Night Countdown , Kylie said she's excited they'll finally be able to "watch Eagles football" as a family.

But even though she's a diehard Philly sports fan , Kylie—who shares daughters Wyatt , 4, Elliotte , 3, and Bennett , 18 months, with Jason—noted that their kids will "continue to root for both" the Eagles and the Kansas City Chiefs, who recently extended their contract with Jason's younger brother Travis Kelce for two more years. Still, don't expect her to cover herself in red, white and gold whenever she decides to go to a Chiefs game with Travis' girlfriend Taylor Swift . In the past, Kylie has refused to wear Chiefs merch out of loyalty for her beloved Eagles—an act of defiance she vows to uphold in the future.

As she noted to E! News, she’s flying for the Eagles "‘Til the day I die." That's why she has teamed up with The Athletic for its "Superstition Swap" campaign , encouraging fellow football fans to share what they do to bring good luck to their favorite teams in return for complimentary access to the outlet's advanced statistics and playoff predictions this season..
