Kylie Kelce announced that she and her husband, ex-Philadelphia Eagles center and current ESPN NFL analyst Jason Kelce, will be welcoming a fourth girl.

She revealed the pregnancy news with an Instagram picture of the couple's three daughters, all of whom wore pink sweaters with "Big Sister" on the front in cursive.

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

The picture featured the Kelces' oldest daughter, Wyatt, with her hands on her head. Their youngest daughter, Bennett, was in tears. However, the middle daughter, Ellie, seemed delighted by the news.

The Kelces received plenty of congratulations in the IG comments, including notes from the Eagles, actress Kaitlin Olsen and Fox Sports lead NFL sideline reporter Erin Andrews.

It's been a busy week for the Kelces, as news also broke that Kylie and Jason Kelce have a duet ("Loud Little Town") on the Eagles' third Christmas album ("A Philly Special Christmas Party"). That album dropped Friday, and it also includes a duet with Jason Kelce and superstar singer-songwriter Stevie Nicks.
