The Mahomes donned matching reindeer onesies for what appeared to be the ‘Miracle on Main Street’ event in Kansas City, which includes ‘pictures with Santa, raffle prizes, vendors, dance performances, the lighting of the Mayor’s Christmas Tree.’

Teammate Blake Bell and his wife Lyndsay were at the bash, too, with the tight end and his partner also matching in green Christmas tree onesies featuring ornament decorations.

On Friday night, neither Kelce nor Swift appeared in any photos but eagle-eyed onlookers spotted the power couple at the event, with a photo of the pop superstar later appearing across social media.

They didn’t seem to be in fancy dress, unlike Patrick and Brittany Mahomes, who held hands as they posed in their costumes which included antlers on top.

‘Falalalalalalalalala,’ Brittany captioned the photo on her Instagram along with a Christmas tree emoji.

The pair also posed with Patrick’s teammate Bell and his wife Lyndsay in another photo.

Kelce, Bell, Mahomes and the rest of the Chiefs roster landed in Wisconsin on Saturday afternoon ahead of Sunday’s game against the Green Bay Packers.

Earlier this week, Swift dashed to see her beau in Kansas City after finishing the South American leg of her Eras Tour.

And the ‘August’ singer is expected to be in attendance this weekend when the Chiefs travel to Green Bay to play the Packers.

The news was revealed by Packers coach Matt LaFleur at his Friday press conference.

‘It is what it is. It comes with it I guess,’ LaFleur said when asked about Swift on Friday. ‘Is she supposed to be here? That’s what I’ve heard. So we’ll see.

‘That’s just part of it, we’re definitely more focused on the game. But I’m sure there’ll be some fired up people in the stands if she shows up.

The pop superstar will get a break from touring with her next ‘Eras’ tour shows not scheduled until February.

After her and Kelce went public with their budding relationship in September, she became a fixture at his games, attending four contests – which were all Chiefs wins.

If she is in fact in the stands for Kansas City’s matchup vs. the Packers, it will be her first game since October 22.
