Kylie took to social media with a photo of their three daughters, Wyatt, Elliotte, and Bennett, each wearing matching pink "big sister" shirts. The adorable photo captured the girls' varying reactions to the news, providing a funny and relatable snapshot of the emotions that come with expanding a family.

Kylie's caption read, "I feel like we captured a very accurate representation of how each of the girls feel about getting another sister. At least Ellie, mom, and dad are on the same page!"

The announcement immediately drew attention, with fans and friends flooding the comments with congratulations and well wishes for the growing Kelce family.

Jason, who has made countless headlines with his NFL success, has also garnered a strong fanbase for his down-to-earth and loving family life, often sharing sweet moments with Kylie and their daughters.

One friend of Kylie and current Fox Sports and NFL on Prime Video reporter Charissa Thompson shared a heartfelt reaction under Kylie's post on Friday night.

Charissa's comment read, "Kylie!!!!!!! Congratulations," followed by plenty of heart emojis.

Thompson had just capped off a tremendous night in Cleveland, Ohio, covering "Thursday Night Football" between the Cleveland Browns and Pittsburgh Steelers, a game blanketed by snow.

She has been a staple in sports media for quite some time, and with Jason now transitioning into a career in sports media, he's adapted quickly as well, working with ESPN and continuing to expand and grow his podcast "New Heights" alongside his brother, Travis.

Most importantly, Jason Kelce is a girl dad, and the major announcement alongside his fan-favorite wife, Kylie, has generated plenty of excitement as they prepare to welcome their fourth child.
