Taylor Swift is a perfect fit for Travis Kelce and his close-knit family, a source tells PEOPLE.

Swift and Kelce, both 34, set the internet ablaze on Sunday when the singer joined her beau on the field after he and the Kansas City Chiefs won the AFC Championship game in Baltimore.

The couple shared a sweet kiss as they celebrated with Kelce’s parents, Donna and Ed Kelce, and his brother, Jason Kelce.

A source close to the couple tells PEOPLE, “It was the best night ever,” and that the “whole family was so, so excited and riding a high,” after Kansas City secured their spot in the 2024 Super Bowl. “Their phones were blowing up all night with congrats. The energy on the field was just insane,” the source adds.

Next, Kelce and the Chiefs will compete against the San Francisco 49ers, hoping for back-to-back Super Bowl wins on Feb. 11 in Las Vegas.

“To be going to Vegas now is indescribable,” says the insider. “Having his family there, all his best friends and managers, and of course, Taylor, celebrating with him was very special.”

The source tells PEOPLE that Kelce “was feeling every single emotion” on Sunday. “Now he and the team are focusing on the Super Bowl.”

According to the insider, “It’s going to be an intense couple of weeks,” as the Chiefs prepare for the Super Bowl. But as Kelce gets through the grueling practices, he’ll have Taylor on his side.

“It’s obvious, isn’t it? They’re genuinely happy together,” the source continues. “She’s there to support him and cheer him on, and she’s fit in seamlessly with everyone he loves.”

And when the 12-time Grammy winner is spending time with Kelce and his family, “They don’t see her as ‘Taylor Swift’ the superstar,” says the source.

After the Chiefs win on Sunday, several photos of Swift lovingly embracing Donna and Ed circulated on social media. Actress Keleigh Teller also shared a photo of Swift posing alongside Donna, Ed and Travis’ brother Jason Kelce, 36.

Swift was later seen with her arm around Ed, who was sporting his son’s Chiefs jersey, as she pointed to Chiefs head coach Andy Reid, who was on stage receiving their AFC Championship trophy.

As for whether or not Swift will be at Allegiant Stadium in Las Vegas when the Super Bowl kicks off, the singer’s attendance is still uncertain due to her tour schedule.

Swift’s Eras Tour resumes on Feb. 7, marking the start of a six-month run across Asia, Australia and Europe before returning to North America on Oct. 18 to finish her final 15 shows.

Despite the 12+ hour flight from Asia to North America, Swift has time zones on her side, which could allow her to make it to Super Bowl LVIII in time to cheer on Kelce and the Chiefs at the game.

Swift’s concert is scheduled for 6 p.m. local time in Tokyo, which equates to 1 a.m. Las Vegas time. Tokyo is 17 hours ahead of Las Vegas; therefore, Swift will save herself time traveling from the show to the game.

Traveling overseas, though, is no impossible task for the couple with respectively busy work schedules. Kelce proved that to be true in November 2023 when he flew to Argentina to support Swift at the Buenos Aires stop of her Eras Tour.
