Brittany Mahomes is standing up for her close friend Taylor Swift, who has been attending football games to support her partner, Kansas City Chiefs tight end Travis Kelce.

In a February 2 Instagram story, the wife of Chiefs quarterback Patrick Mahomes shared a Yahoo Sports post that quoted former NBA player-turned-sports-commentator Charles Barkley.

"If you're screaming at Taylor Swift saying she ruined (football), you're just a loser," read the quote from Barkley.

Under the post, Brittany Mahomes wrote three simple words: "Let. Them. Know."

Mahomes' defense of Swift comes after the two were seen together wearing matching hats following the Chiefs' AFC championship win against the Baltimore Ravens, which secured them a spot in Super Bowl LVIII on February 11.

Back in November 2023, Brittany Mahomes made her friendship with Swift Instagram official by posting a photo of herself posing with Swift, Bell, and Paige Buechele, who is the wife of former Chiefs backup quarterback Shane Buechele.

The photo was posted two days after the trio was seen leaving Swift's Tribeca apartment, coinciding with the day the Chiefs defeated the Miami Dolphins in the NFL's inaugural match in Germany.

With various Instagram posts and outings on both coasts, it seems that a friendship is developing between Swift and the mother of two. Here's what you need to know.
