The Kansas City Chiefs quarterback put on his fourth annual gala through the ’15 and the Mahomies Foundation’ – the charity he established five years ago to help improve the lives of children.

Given he is one of the most famous athletes on the planet, Mahomes was able to invite a plethora of high-profile figures to his latest event, which included a glitzy auction on Saturday night followed by a golf competition on Sunday.

His Chiefs teammate Travis Kelce attended both fixtures, rocking up to the auction with his pop-megastar girlfriend Taylor Swift before taking to the course 24 hours later.

In a video shared by Mahomes on Instagram, Kelce can be seen laughing and joking as he enjoys a round of golf with the quarterback and their Kansas City colleague Justin Reid.

He is then shown entering the auction hand-in-hand with Swift, where they were followed by the likes of UFC fighters Justin Gaethje and Khalil Rountree Jr, golfer Tony Finau and former NFL players Andrew Whitworth and Kyle Rudolph.

Mahomes’ wife Brittany was also in attendance, sitting alongside Swift as the auction took place.

Brittany, who was recently ripped for allegedly putting on a front with Swift,  became a close pal of the pop star’s this past NFL season and even hung out with her and her high-profile girl squad in New York on previous occasions. What’s more is that Brittany and Swift have gone to multiple Chiefs games together.

Kelce stole the show on the night, first drawing cheers when he referred to Swift as his ‘significant other’ while auctioning four tickets for her Eras Tour.

‘I think, um, I was just talking to my significant other,’ he said at The 15 and Mahomes Foundation Golf Classic gala in Vegas on Saturday. ‘We might have one other auction item that wasn’t on the docket.’

Later in the evening, the legendary Kansas City tight end also combined with Mahomes for a hilarious touchdown pass which flew right past the various tables.

Mahomes’ video shows Kelce producing the catch while suited and booted, another moment which sparked applause in the audience.

At the end of the video, the quarterback can be seen sinking a putt on the golf course before celebrating passionately.

Kelce partied the night away in Vegas on Saturday night after attending the charity event, but there was no sign of Swift.

Just hours after the couple rocked up at the gala together, Travis headed to the packed XS Nightclub to join Norwegian DJ Kygo behind the decks at his Vegas party, with Swift nowhere to be seen on the night.

In a selection of photos and videos shared by Kygo, the Chiefs star can be seen taking the microphone to ramp up the crowd at the event, before waving a t-shirt in the air and jumping up and down to the music.

Travis also posed for a photo alongside the music producer and his manager Myles Shear while living it up at the Wynn Hotel’s famous nightclub.
