Taylor Swift and Travis Kelce made a striking appearance at Patrick and Brittany Mahomes’ charity auction event,

where the Kansas City Chiefs tight end referred to the pop singer as his ‘significant other.’

‘I think, um, I was just talking to my significant other,’ Kelce said, whetting the audience’s appetite for a highly coveted auction item –

four tickets to her Eras Tour – at The 15 and Mahomies Foundation Golf Classic gala in Las Vegas on Saturday.

‘We might have one other auction item that wasn’t on the docket.’

Swift and Kelce were on hand as guests of Mahomes and his wife, Brittany, who was ripped by one insider for allegedly putting on a front with the pop star. The Chiefs QB’s wife became a close pal of Swift’s this past NFL season and even hung out with the singer 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.

‘[Brittany] has too many red flags and people are starting to see through her fake and bitchy persona,’ one inside source told DailyMail.com. ‘She is an opportunist who is clearly not a girl’s girl.’

In a video shared on X, Swift can be seen waving a napkin from her chair while Kelce and auctioneer Harry Santa begin auctioning off the tickets.

Santa then said to Kelce, as the camera focused on the pair: ‘Who would actually pay hundreds of thousands just to know Taylor Swift is actually cheering you on as you’re winning 4 of her tickets – this is insane! Let’s go!’

Kelce laughed in response, as he waved a napkin, just like his ‘significant other.’

He also yelled ‘Let’s go baby!’ at one point, as tickets for Swift’s shows eventually sold for a mouthwatering $80,000, as indicated on Santa’s Instagram Story.

Earlier in the evening, Kelce and Swift were seen arriving at the event together in a video shared on X by another gala attendee. The pair held hands while making their way past guests to join the Mahomes at a table.

The couple were described as ‘super adorable’ and ‘down to earth’ by the attendee in the caption of her footage.

‘NBD. Just T Swift and her man Travis Kelce,’ they wrote over the video.

‘And they are super adorable together. So down to earth & Kind … Just super cool badass human beings.’

Just 24 hours before the gala on Friday, Kelce and Swift, who released her new album The Tortured Poets Department on April 19, were spotted on a double dated with the Mahomes at Easy’s Cocktail Lounge inside the ARIA Resort & Casino on the Las Vegas Strip.
