Taylor Swift is said to be becoming part of the Kelce family amid her romance with NFL star Travis Kelce. 

The popstar, 34, was spotted cheering on her Kansas City Chiefs beau at

his games alongside his family members throughout the NFL season as their relationship continued to flourish.

The songstress has sat alongside his mom Donna at multiple games with the two first spotted together

in an Arrowhead suite during the Chiefs’ Week 3 win over the Chicago Bears – the first she attended.

Meanwhile, the 14-time Grammy Award winner finally met Travis’s brother Jason and his wife Kylie during Kansas City’s playoff win over the Buffalo Bills in January.

And the Anti-Hero hitmaker has clearly used the game days to bond with her boyfriend’s family amid a report she’s been welcomed with open arms.

‘Both of their families love them as a couple and Taylor has become even more close with Travis’ mom, [Donna],’ a source told Us Weekly. ‘Taylor has really been integrated into the family.’

Taylor is also said to have enjoyed getting to know Kylie and Brittany Mahomes – the wife of Chiefs quarterback Patrick Mahomes.

The singer and Kylie, who is married to retired Philadelphia Eagles legend Jason Kelce, posed for photos together at both the Chiefs’ Divisional Round win over the Bills at Highmark Stadium and the team’s AFC Championship upset victory over the Baltimore Ravens.

It appeared Kylie has been initiated into Swift’s game-day girl squad as she sat in the center of one photo with Taylor hugging A-List pal model Cara Delevingne to her right and Keleigh Teller, wife of actor Miles Teller, flashing a peace sign in front of her.

Meanwhile, Taylor quickly struck up a close friendship with Brittany after she began cheering on Travis from the stands.

The pair have been almost inseparable since Swift and Kelce took their relationship public and even debuted a personal handshake to celebrate Chiefs touchdowns in October.

Brittany also appears to have been accepted into Taylor’s inner circle, as she joined her friend group of Selena Gomez, Gigi Hadid and Sophie Turner out for dinner in New York City in November.

‘They have fully embraced her. It’s a whole new world and chapter for her,’ the source added.

Travis and Taylor took their relationship public in September and the pop superstar has been a regular fixture at his games throughout last season, including the Super Bowl.

‘Travis and Taylor are still in the ‘honeymoon’ phase and the relationship is serious,’ the source said. ‘They are on the same page about the future but are not rushing marriage or the next step.’

Since entering the offseason following the Chiefs’ third Super Bowl win in five years, Travis has repaid Taylor’s support by playing the role of doting boyfriend.

The tight end jetted to Sydney and Singapore over the past month to watch her perform her Eras Tour.

‘Travis is going the extra mile to make sure he is showing support for Taylor during his off time,’ the insider notes. ‘He is so happy he can be there for her, and show up for her even during the international leg of her tour.’
