Singer Este Haim said she, sister Alana Haim and Taylor Swift were surprised by the mass attention their matching blue and orange shirts received at Game 4 of the NBA Finals on June 10.

During a Tuesday interview with Variety, Este shared the behind the scenes of their “magical” night on Celebrity Row at Madison Square Garden, where the Knicks pulled off the biggest comeback in NBA Finals history over the Spurs in Game 4.

“I mean I think it surprised all of us,” Haim told Variety while at the Los Angeles premiere of “Voicemails for Isabelle” on Netflix on Tuesday. “I just went into being like were going to go to a basketball game and have fun, thats literally it.

“Taylor invited me and Alana. I’ve never sat courtside ever, so it was a magical experience.

“I’ve never heard the Garden be that loud in my life. It was amazing. I had the best time.”

The Haim sisters and Swift sported blue shirts with Knicks-coded puns on the front in orange.

Swift’s shirt said “Stevie Knicks,” which was a nod to the legendary singer, who she’s been friends with for some time.

Este’s shirt, “Knickole Kidman,” was a reference to actress Nicole Kidman.

Alana donned a shirt with “Knickelback,” a twist on Canadian rock back, Nickelback.

They were courtside with actress “Law & Order: SVU” star Mariska Hargitay — a close friend of Knicks point guard Jalen Brunson — who also donned a “Stevie Knicks” shirt.

Swift, Este and Alana were seen jumping up and down in the back hallways of MSG with the Knicks’ Seventh Ave Squad — the team’s entertainment team — after the Knicks rallied from a 29-point hole in the third quarter to beat the Spurs 107-106.

Swift, who owns multiple properties in New York City, and her fiancé, Chiefs tight end Travis Kelce will tie the knot at MSG on July 3.

The couple reportedly paid nearly $3 million to rent out the world’s most famous arena for three days.
