Taylor is decking the halls of The Forum in Los Angeles, but her rocking her BFF band's Christmas sweater is what gives us all the holiday cheer!

Taylor Swift is getting into the spirit of the season with one of the most important components of the holidays -- friendship!

The Reputation singer documented her soundcheck and preparations for her show at iHeartRadio's Jingle Ball on Friday at The Forum in Los Angeles -- which will also feature performances from Demi Lovato, Ed Sheeran and more -- and the Christmas sweater she wore made our heart grow three sizes, reading, "It's the most wonderful HAIM of the year."

"OK BUT HOW CUTE IS @taylorswift13 IN @HAIMtheband MERCH!!!!" one fan on Twitter noted, giving props to how Taylor called out her BFFs in the sister trio soft rock group.


And at one point during soundcheck, Taylor's crew gave her a spook at the "She's dead!" part of her lead Reputation single, "Look What You Made Me Do."

And as it turns out, that tune -- which is immortalized by Zombie Taylor killing her old selves -- makes for an unlikely festive song this holiday season.

"Do you think Taylor wrote the line I check it once I check it twice so she could use it when Christmas rolls around," one fan pondered on Tumblr, prompting Taylor herself to reply, "Finally someone noticed."

So perfect, we new Swiftmas would come early this year!
