Jason Kelce's daughter Bennett cheers on dad at 1st NFL game

Jason and Kylie Kelce are parents of three daughters.

Sunday night was a family affair for Philadelphia Eagles starting center Jason Kelce as his team took on the Los Angeles Rams on the Eagles' home turf.

Kelce's wife Kylie and their daughters Wyatt, 4, Elliotte, 2, and Bennett, 7 months, were in the stands at Lincoln Financial Field along with their extended family, including Jason Kelce's mom Donna Kelce.

Kylie Kelce shared three snapshots of their family outing and revealed it was their youngest daughter Bennett's first time at an NFL game.

"We were celebrating a 4th birthday when the Birds went 4-0. It was also Bennie's first game (outside of my body)," the mom of three wrote in an Instagram caption, referencing Wyatt's recent birthday and her pregnancy with Bennett during the Super Bowl in February.

Donna Kelce chimed in with her own reply. "And now they are 5 and 0!!!!! Whoo hoo!" the mom of two commented, pointing out that the Eagles now have a five-win record after the fifth week of the NFL's regular season.

Bennett was born Feb. 23, a week and a half after her father and uncle, Kansas City Chiefs tight end Travis Kelce, faced off at Super Bowl LVII, a first in NFL history. She'll turn 8 months old this October.

In a March episode of the brothers' "New Heights with Jason and Travis Kelce" podcast, Jason Kelce revealed that Bennett, whose middle name is Llewellyn, was named after their grandmother Mary and her maiden name.

The Eagles are scheduled to play the New York Jets next Oct. 15 at MetLife Stadium in New Jersey.
