A very merry Swiftmas! Taylor Swift and Travis Kelce had festive celebration with their parents at NFL star’s mansion after Chiefs game – and popstar told friends combined family gathering was her ‘most meaningful’ holiday yet

The families of Taylor Swift and boyfriend Travis Kelce gathered at his Kansas City mansion for a festive Christmas celebration, an insider has revealed to DailyMail.com.

On Christmas Day, Taylor's mom and dad Scott, 71, and Andrea, 65 — along with her brother Austin, 31 — cheered on Travis' team, the Kansas City Chiefs, at Arrowhead Stadium, where his side ultimately suffered a loss to the Las Vegas Raiders, 20-14.

After the defeat, photos surfaced of Taylor's father Scott watching the game with Travis' father Ed, 69. The two men were chatting and DailyMail.com has exclusively learned that their conversation did not end when the game ended.

A source close to the Anti-Hero singer revealed that Taylor's family joined Travis and his father at the NFL's Kansas City mansion after the game, where they all celebrated the rest of the holidays together.

“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 Award winner told DailyMail.com.

'She has never experienced this before and it made the holiday the most meaningful for her.

“Her friends think this is even more proof that Travis will be a Swiftie for life.

'Travis was obviously disappointed that they didn't win the game. But he's at a point in his career where he's not letting it affect him too much and he's looking forward to the next game.”

Missing from the pack was Travis' mother Donna, 71, who Taylor has grown close to in recent months.

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

Afterwards, Donna would fly back to Kansas City, where Taylor's family has been staying since Christmas.

Before the game, Donna told People, “I'll be in Philadelphia for Christmas, spending time with my grandkids as we cheer on their dad.”

She was of course referring to 36-year-old Jason, who plays as a 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 travel to Kansas City after the game to spend time with “family, friends and Chiefs fans.”

Although she was away from her husband and the Swift family on Christmas Day, the source told DailyMail.com that she did indeed fly back to Kansas City to meet Taylor's parents.

As fans know, the first time Taylor's parents would meet was in November, when the Kelce brothers' teams – the Chiefs and the Eagles – faced off.

But Taylor had to withdraw from attending the match, as did her parents, when one of her fans, 23-year-old Ana Clara Benevides, died of heat exhaustion ahead of Taylor's Eras Tour show in Rio de Janeiro.

Donna and Taylor have met before: the first time the singer was at 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 huge football guy, he played college ball. I think a year in Hawaii and then a year or two – I forget how long he was there – in Delaware,” Kelce revealed about Swift's father on the brothers' New Heights podcast.

“I think he was a center linebacker … he's a tall guy, about 6-foot-4.”

Jason, one of the most high-profile centers in professional football, responded: “We're going to have to get together one day and talk about a center thing.”

On Wednesday, Travis and Jason sent Taylor's fans on red alert when they teased the possibility of her appearing on their podcast next Friday.

Revealing the news, Travis said: 'We have a guest episode coming up… for you 92% for being so loyal and joining in every week and being such fans of the Kelce household, we have a Kelce family at the end of the year's holiday spectacular. It drops this Friday.

“It's going to be a revolving door of Kelce family members stopping by to talk to us and we can't wait to share it with you this Friday.”

The Chiefs game on Christmas Day was record-breaking, with the NFL bringing in its largest number of viewers on the holiday since 1989 — coincidentally the name of Taylor's fifth studio album.

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

In a recent interview with CBS, the Kansas City Chiefs quarterback gave his reaction to Taylor and Travis' romance, saying she has been good for him and for the team.

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

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

“And then he started bringing Taylor along and he realized how cool of a person she was, and she is, and so for us there were a few jokes here and there in the beginning.”
