After the loss, photos emerged of Taylor's father Scott watching the game with Travis' father Ed, 69. The two men were seen chatting vigorously and has exclusively learned that their conversation didn't end when the game ended.

“Seeing their families together on such a special holiday was the best gift ever for Taylor,” a source close to the 34-year-old Grammy winner told .

“This has never happened to her before and it made the holiday the most meaningful for her.”

“Her friends believe this is just further proof that Travis will remain a Swiftie for life.”

“Obviously Travis was bummed they didn’t win the game. But he’s gotten to the point in his career where he doesn’t let it get him down too much and he’s looking forward to the next game.”

Missing from the group was Travis' mother Donna, 71, with whom Taylor has developed quite a close bond in recent months.

She was in Philadelphia on Christmas Day supporting her other son Jason's team, the Philadelphia Eagles, as they played the New York Giants. The Eagles ultimately won 33-25.

Afterwards, Donna was scheduled to fly back to Kansas City – where Taylor's family has stayed since Christmas.

Before the game, Donna told People: “I'll be in Philadelphia over Christmas spending time with my grandchildren while we cheer on their dad.”

She was, of course, referring to 36-year-old Jason, who plays center for the Philadelphia Eagles. Jason and his wife Kylie share three-year-old Wyatt, two-year-old Elliott and nine-month-old Bennett.

Donna told the outlet that she would be traveling to Kansas City after the game to spend time with “family, friends and Chiefs fans.”

Although she wasn't with her husband and the Swift family on Christmas Day, the source told that she actually flew back to Kansas City to meet Taylor's parents.

As fans know, the first meeting between Taylor's parents was expected in November when the Kelce brothers' teams – the Chiefs and the Eagles – competed against each other.

But Taylor, like her parents, had to miss out on attending the game when one of her fans, 23-year-old Ana Clara Benevides, died of heat exhaustion before Taylor's Eras Tour show in Rio de Janeiro.

Donna and Taylor have met several times – the first time the singer attended a Chiefs game, she stood next to Donna in the Kelce Suite at Arrowhead Stadium.

Scott and Travis have also met before – and were spotted together at one of Taylor's shows in Buenos Aires, Argentina, earlier this month.

“He's a big football guy – he played college ball.” “I think a year in Hawaii and then a year or two – I don't remember how long he was there – in Delaware,” Kelce revealed The brothers' New Heights podcast about Swift's father.

“I think he was a linebacker turned center…he's a big guy – about six feet tall.”

Jason, one of the most well-known centers in professional football, responded: “We'll have to sit down someday and talk about center shops.”

On Wednesday, Travis and Jason sent Taylor's fans on alert when they hinted that she might appear on their podcast next Friday.

When Travis revealed the news, he said, “We have a guest episode coming up…for you 92%, because you're so loyal, you tune in every week and you're such fans of the Kelce household, we have a Kelce family.” -End of the year.” Vacation spectacular. It's coming out this Friday.

“It will be a revolving door of Kelce family members coming by to talk to us and we can’t wait to share it with you this Friday.”

The Chiefs' Christmas Day game was a record-breaking one, as the NFL drew its largest viewership on the holiday since 1989 – coincidentally the name of Taylor's fifth studio album.

After the Chiefs' loss to the Raiders, Taylor was seen comforting his new girlfriend Brittany Mahomes, 28, the wife of Kansas City quarterback Patrick, 28.

In a recent interview with CBS, the Kansas City Chiefs quarterback expressed his reaction to Taylor and Travis' romance, saying that it was good for him and for the team.

“She’s just a part of Chiefs Kingdom and part of the team,” Mahomes told CBS’s Nate Burleson.

“At first I felt like everyone was kind of staying away and just letting him do what he did,” Mahomes added, describing the beginning of the relationship earlier this fall.

“And then he started bringing Taylor around and he realized what a cool person she was and is, and so we had a few jokes here and there in the beginning.”
