Brittany and Patrick Mahomes had an “epic” double date in Las Vegas as they celebrated their charity’s work.

On Saturday, April 27, the couple attended the 15 and the Mahomies Foundation Golf Classic gala at the Bellagio Hotel, where they were joined by Patrick’s teammate Travis Kelce and his girlfriend Taylor Swift, among other current and former athletes who support the children’s charity.

Brittany, 28, shared a carousel of photos from the night with her husband, 28, writing on Instagram, “Last night was Epic.”

Brittany, who shares daughter Sterling, 3, and son Bronze, 1, with the quarterback, thanked everyone who supports the charity in the caption. “If you were there, THANK YOU! We could not do this without all of our communities we are apart of and all the people that choose to support @15andmahomies .”

Patrick also posted a highlights reel of the charity event on his own Instagram, calling it “a great weekend.” Brittany replied with a series of clapping hands emojis.

For the gala, Brittany wore a figure-hugging pastel yellow dress with cutouts at her sternum and her décolletage that was adorned with two flowers, while her husband, who started the charity in 2019, wore a blue plaid suit jacket and pants with a white button-down top.

Along with the Mahomes’, Kelce, 34, and Swift, 34, golfer Tony Finau, UFC fighter Khalil Rountree Jr., and former NFL players Andrew Whitworth and Kyle Rudolph were among the stars in attendance at the gala, where the pop star made a huge donation to fundraise for the 15 and the Mahomies Foundation.

In a video posted by the night’s auctioneer Harry Santa-Olalla on his Instagram Stories and in a clip shared on TikTok, Kelce took to the stage during the gala to auction off some very special tickets.

“I was just talking to my significant other, and we might have one other auction item that wasn’t on the docket,” Kelce said in the video, before asking guests, “Has anyone heard of the Eras Tour?”

In a video posted on X (formerly Twitter) from the gala, Swift, who was seated beside Patrick and Brittany, waved what appeared to be a red napkin from her seat as Kelce and Santa-Olalla began auctioning off her concert tickets.

“Who would actually pay hundreds of thousands just to know that Taylor Swift is actually cheering you on as you’re winning 4 of her tickets?” the auctioneer asked the excited crowd in the video. “This is insane! Let’s go!”

The set of four tickets — valid for any of Swift’s upcoming U.S. tour dates — were eventually sold for a $80,000, Santa-Olalla shared in a caption of an Instagram post about the gala.

Later in the night, Kelce and Patrick got in on the fun, too, as they signed footballs and the quarterback started throwing them at Kelce, who caught them easily with one hand.
