It makes the whole place sparkle.

Taylor Swift and Travis Kelce came out to support their friends at the fourth annual Patrick Mahomes 15 and Mahomies Foundation Golf Classic on Saturday, and the pop star showed off a dazzling look for the charity event.

The “Fortnight” singer, 34, dazzled in a metallic blue Maria Lucia Hohan dress ($2,405) while tightly holding hands with the Kansas City Chiefs alum, 34, at the Bellagio Hotel from Las Vegas.

The dark blue model features a gathered bodice and thin straps, tied at the back with lace details.

While the Grammy winner — who was seated with host and quarterback Patrick Mahomes, 28, and his wife, Brittany Mahomes, 28 — chose a designer dress for the gala, she paired it with a necklace surprisingly affordable.

Swift chose Vitaly’s $120 Shimmer Necklace, a unisex style that features two different styles of chunky gold chains connected by a paperclip-style link and a dangling crystal.

The “Shake it Off” singer is no stranger to ups and downs, having repeatedly paired affordable pieces with high-end design over the years, like her Mazin jewelry for under $100, her Dollar favorite.

As for Kelce, he looked dapper in a dark suit and shirt with no tie — and the 2024 Super Bowl champion announced a special auction item from his famous girlfriend at the event to follow up.

“Okay, okay, I think I just talked to my lover and we might have another replacement that’s not planned yet,” Kelce told the crowd, adding, “Um, someone has he heard of the Times Tour?

Auctioneer Harry Santa-Olalla then auctioned off four tickets to one of Swift’s upcoming US tours – and an anonymous winner bought them for a whopping $80,000.

The “Down Bad” singer and NFL star also partied with the Mahomes in Vegas, enjoying a night out at the Aria Resort & Casino before a gala to raise money for children in need.
