Taylor Swift reps ‘Stevie Knicks’ with her shirt at Game 4 of the Knicks vs. Spurs NBA Finals

Taylor Swift’s sideline style is always a slam dunk.

And all eyes were on the “I Knew It, I Knew You” songwriter ahead of Game 4 of the Knicks vs. Spurs NBA Finals on Wednesday, with Swift arriving at Madison Square Garden wearing a blue baby tee that read “Stevie Knicks.”

The 14-time Grammy winner was joined by close pals Este and Alana Haim — who repped “Knickole Kidman” and “Knickleback,” respectively, with their matching shirts.

Page Six exclusively reported this morning that Swift would be at the game, with a source telling us, “She’s a huge fan of the Knicks and really wants to be there to support them. She is going with friends.”

While Swift’s become a fixture at fiancé Travis Kelce’s Chiefs games — almost always dressed in the Kansas City team’s colors or vintage merch — the couple made a courtside cameo in Kelce’s native Cleveland during the NBA Eastern Conference Finals late last month, watching the Cavaliers face off against the Knicks.

They coordinated in his-and-hers denim for the game at Rocket Arena, with Swift sporting a chain-accented tank top from Stella McCartney’s recent H&M collaboration along with a patchwork denim jacket, wide-leg jeans and heeled sandals from the designer’s primary collection.

A black Dior Cigale bag finished her game-day outfit.

Kelce opted for a short-sleeved Louis Vuitton denim shirt and pants, Nike LeBron 7 MVP sneakers in Cavaliers colors and a Just Don x Mitchell & Ness hat emblazoned with the Cleveland team’s name and logo.

While the tight end couldn’t make it to tonight’s game on account of his pre-season training schedule, he’ll be back at Madison Square Garden soon enough: As Page Six revealed last week, Swift and Kelce are set to marry at MSG over Fourth of July weekend.
