Taylor Swift gave Dave Portnoy a big surprise this weekend — a letter written by the pop superstar thanking him for all his support.

Portnoy — the self-proclaimed “king of the Swifties” — received the handwritten note from Taylor’s brother, Austin, who personally delivered it to the Barstool Sports owner before he attended the singer’s Eras Tour concert in Miami on Saturday.

Portnoy was so excited, his podcast “BFFs” posted the letter to Instagram on Sunday with the caption: “What a gift from @taylorswift to @stoolpresidente at the Eras Tour last night.

On the front of the white envelope, Taylor scrawled “Dave!” with a star drawn next to his name. On the back, there was a green wax seal highlighting her lucky number, 13.

In the note, Taylor wrote that she was thrilled that Dave would be on her show on Saturday — and thanked him “for always being supportive, loyal, and having my back when so many people didn’t.”

On that last point, Taylor appeared to be alluding to some of the backlash she faced in September when she endorsed Kamala Harris over Donald Trump in the 2024 race for the White House.

At the time, Portnoy came to Taylor’s defense despite his support for former President Trump.

He posted a message to “X,” telling his many fans that people can vote for whoever they want in this country and that he won’t change his opinion of them because “everyone has their own opinion.”

Now it looks like Dave and Taylor are on their way to becoming lifelong friends.
