Taylor Swift and her boyfriend, Kansas City Chiefs tight end Travis Kelce, put on a strong united front as they left Lucas Oil Stadium in Indianapolis, IN on Saturday following her concert.

The power couple of 15 months – who held hands while waving to fans – were curiously being followed by a camera crew and a boom operator.

The 35-year-old footballer was spotted by fans in the VIP section with the 34-year-old pop star’s mother Andrea Swift enjoying her performance of So High School.

Travis also mingled with his buddy – former Kansas City Chiefs tight end Ross Travis – as well as NSYNC boybander Joey Fatone and his girlfriend Izabel Araujo.

‘@taylorswift puts on one heck of a show!’ the 47-year-old Grammy nominee gushed via Instastory.

‘Congrats to her and her crew!’

Taylor’s final song of the night was Karma and she gave Kelce a shout-out: ‘Karma is the guy on the Chiefs coming straight home to me!’

Swift – whose three-night stand at the Lucas Oil Stadium ends Sunday night – will conclude her $1.93B-grossing, 149-date The Eras Tour at BC Place in Vancouver on December 8.

The 14-time Grammy winner has just two more archival albums (Taylor Swift and Reputation) to re-record after losing the rights to the first six of her master recordings by her underhanded ex-manager Scooter Braun, who’s since retired from the music industry.

The three-time Super Bowl champ and his team will next face off against the Tampa Bay Buccaneers at Arrowhead Stadium in Kansas City, MO on Monday night.

Taylor and Travis’ sighting came hours after his big brother Jason Kelce defended his honor against a rude heckler by repeatedly uttering a gay slur.

The retired NFL center – turning 37 this Tuesday – was leaving the Penn State vs. Ohio State game at Beaver Stadium in State College, PA when a man in a navy-blue hoodie shouted: ‘Kelce, how does it feel that your brother is a fa**** for dating Taylor Swift?’

At that, Jason turned around to face the unidentified man, grabbed his iPhone, and smashed it face down on the street before stealing it.

When the heckler pleaded ‘Give me my phone, bro,’ Kelce shouted back: ‘Who’s the fa**** now? Who’s the fa**** now? Who’s the fa**** now?’

It’s unclear if the hot-tempered New Heights podcaster ever returned the broken phone to the man.

Jason is father to three daughters – Wyatt, 5; Elliott, 3; and Bennett, 20 months – from his six-year marriage to field hockey coach Kylie McDevitt.
