Jason Kelce admitted he and brother Travis may have had some help when it came to their showstopping karaoke duet – and it came from an expert source.

The Philadelphia Eagles legend stepped up to help his younger sibling defend his title at the American Century Championship this week. However, their performance came on the stage, rather than the golf course.

The duo teamed up to bring the house down with their rendition of Bob Seger’s 1978 hit ‘Old Time Rock & Roll,’ at the celebrity golf tournament’s annual karaoke competition on Thursday night.

And the retired NFL center revealed that Travis’s pop sensation girlfriend, Taylor Swift, influenced their performance.

‘Taylor’s given us tips before but Travis has won it five times, so he’s a karaoke expert in his own right,’ Jason told Access Friday. ‘He was definitely telling the dance routine – which I screwed up – but we had some fun with it.’

‘Gosh, we just had fun,’ Travis added when asked how he and his brother applied the songstress’ tips when they stepped into the spotlight.

The siblings’ performance proved to be a true crowd pleaser, peaking when they broke out into a choreographed dance break, busting out moves including a line dance and air guitar.

Travis punctuated his performance with the occasional hip thrust as he serenaded the audience, while Jason, dressed in a golf shirt with the sleeves ripped off and a cowboy hat, sprinkled in a sidestep as he amped up the crowd.

However, the efforts weren’t enough for Travis to claim the crown for a second year running as he was dethroned by Ray Romano’s rendition of ‘Lose Yourself’ by Eminem.

Travis is no stranger to the stage, having joined his pop sensation girlfriend Swift in a surprise cameo on her Eras Tour at Wembley Stadium last June.

The tight end also belted out Whitesnake’s 1982 hit ‘Here I Go Again’ and received a huge reception from the crowd in Lake Tahoe last year, before he was eventually named the winner.

As he accepted his award, Kelce hilariously gave a shout-out to the 14-time Grammy Award winner in a video which quickly went viral on social media.

After jumping up and down with excitement and pretending to cry, he threw one arm in the air and shouted: ‘Taylor this is for you!’

The karaoke night took place Thursday the night before the real action got underway. Travis and Jason took to the course Friday as one of the last groups to tee off alongside former NFL tackle and Amazon Prime analyst Andrew Whitworth.

In DailyMail.com video, Jason, sporting his signature on-course straw hat and a black polo, is seen stepping on to the tee box with an iron. The Philadelphia Eagles legend then just narrowly sent his shot creeping into the rough on the right handside.

Meanwhile Travis, dressed in a clay green Nike tour polo and white cap, also addressed his ball with an iron in his hand and fired his crisp shot safely into the fairway.

However, the hole quickly unraveled for the Kansas City Chiefs star as he almost struck the crowd with his approach shot into the green at the opening par-4.

The NFL siblings were supported by their father, Ed Kelce, as he watched on from the fringes of the fairways.

And the Kelce patriarch may not be the only special guest. Travis and Jason took to the fairways amid speculation that the tight end’s A-List girlfriend Taylor Swift could make an impromptu appearance on the banks of Lake Tahoe.

Travis and the pop sensation have been popping up across America this summer, with the songstress recently surprising fans with an unplanned performance at Kelce’s Tight End University in Nashville.

And rumors of another surprise appearance reached fever pitch Thursday when Entertainment Today host Kevin Frazier appeared on The Dan Patrick Show and appeared to hint at a secret ‘event’ the pair have planned over the next few days.
