Taylor Swift donned red to cheer on her boyfriend, Travis Kelce, at the latest Chiefs game.

The 33-year-old superstar was spotted at Lambeau Field in Wisconsin Sunday rocking a red teddy coat layered over an all-black outfit in support of tight end Kelce, 34, during the Kansas City Chiefs' game against the Green Bay Packers.

Completing her game day attire, she wore her signature red lip, a matching red manicure, and a gold chain necklace.

However, the vibrant red Stella McCartney outerwear bore a striking resemblance to the trench Brittany Mahomes sported during a Chiefs game in support of her husband, quarterback Patrick Mahomes, in November last year while she was pregnant.

This led some fans to speculate that the 12-time Grammy winner may have borrowed the coat from her pal.

"We love friends who share CLOTHES!!!" one user wrote on X, formerly Twitter.

"I think probably [T]aylor doesn't have all her clothes with her and finding this shade red coat may not be easy!" speculated the user in a second tweet. "In the pap pic of Brittany getting on the plane you can see her holding a red [item]."

"[I]'m sobbing," wrote another fan. "Taylor's wearing [B]rittany's coat."

"[T]aylor with [B]rittany's coat and Brittany with the little braids aaa so cute," another fan gushed.

However, some fans opposed the claim, suggesting that the "Cruel Summer" singer likely wouldn't fit into Brittany's coat due to their height difference.

"[H]ow could [people] logically think that [B]rittany's coat would fit [T]aylor when she's like 20cm taller than [B]rittany and the coat still looks oversized on blondie[?]" a social media user asked.

"Brittany's would be way too short for Taylor. Look at the Brittany's coat length and look at Taylor[']s. Right lengths for both. They just have the same coat!!!" wrote another user.

"[G]uys, [I don't know] about [T]aylor borrowing that coat from [B]rittany, it's [S]tella [M]cCartney! [T]aylor could've also had it in her possession for YEARS," a fan suggested.

Swift and Brittany, who also sported a red and black jacket, were captured on camera enthusiastically cheering for the Chiefs in a private suite at the stadium Sunday.

They were also seen arriving at the venue together.

Their blossoming friendship has been making headlines since September, coinciding with the public acknowledgment of Swift and Kelce's relationship.
