SPECIAL MOMENT: Travis Kelce’s mother surprises everyone by wearing a plum red outfit to Taylor Swift’s party….

So scarlet it was maroon.

Donna Kelce was one of many guests in attendance at Taylor Swift’s surprise Eras Tour wrap party recently.

And Travis Kelce’s mom certainly dressed on theme, wearing a sparkling monochromatic outfit that seemed to reference the song “Maroon,” a fan favorite from Swift’s 2022 album “Midnights.”

The mom of two wore a Jingle Belles by Kim Gravel sequined top ($64) and faux leather pants ($60 $50), both from Donna’s beloved QVC.

She wore the same pants with a very similar sparkling top and bomber jacket at the premiere of Travis’ Hulu show, “Grotesquerie,” in September.

The Hallmark movie actress cut up the dance floor in photos posted by Travis’ BFF Aric Jones, one of many friends who showed up at the event.

Travis, meanwhile, revived the tuxedo and top hat he wore during his onstage Eras Tour cameo in London in June, and Chiefs teammate Patrick Mahomes matched in the same look

Brittany Mahomes channeled 2008’s “Fearless” in shimmering fringe, and friend Ashley Avignone wore a faux snake around her neck in honor of “Reputation.”

And Swift showed up in a black A-line Balmain minidress and $36,000 diamond earrings from De Beers.

Donna has grown close with her son’s girlfriend over the course of their relationship, with the pair sitting side by side at Arrowhead Stadium for many games and spending Thanksgiving together last month.

She’s also attended her fair share of Eras Tour concerts — both with and without her son — and was in the audience during his viral cameo in London.

She’s even worn tributes to Tayvis, including a Chiefs hat embroidered with Taylor’s and Travis’ birth flowers, and often can be seen wearing her gold “Tortured Poets Department” bracelet.
