Let’s hear it for New York.

Alicia Keys wore a rhinestone-studded black leather Pelle Pelle jacket, matching leather pants and an eye-popping diamond “K” chain to close the Knicks parade at City Hall on Thursday, paying tribute to her hometown team and its historic championship.

The Manhattan-born Grammy winner, 45, performed “New York State of Mind” and her and Jay-Z’s 2009 anthem “Empire State of Mind” for the crowd, as exclusively reported by Page Six earlier this week.

She wore her hair slicked back in a twisted double ponytail, showing off shoulder-grazing diamond hoop earrings.

It was the second Knicks-themed outfit Keys has pulled out this week. At the closing night of the Tribeca Festival on Saturday — which doubled as an impromptu victory party after the team clinched the title — she took the stage in a blue version of the same Pelle Pelle leather jacket.

The brand’s For The City of Knicks jacket, created in partnership with Allan Houston’s FISLL social-impact brand, is currently available in a limited-edition women’s cropped version for $1,675. The piece is heavily embellished with orange patches, a bedazzled “New York” across the front and the Knicks logo stitched on the back.

Keys — who grew up in Hell’s Kitchen, blocks from Madison Square Garden — had to miss the team’s Game 5 clincher in San Antonio for the premiere of her documentary “Girl From Hell’s Kitchen.”

But the lifelong Knicks fan wasted no time celebrating afterward, sharing videos of fans singing “Empire State of Mind” on the streets and writing on Instagram, “It’s a New York moment!!!!!! The @nyknicks are officially world champions.”

On Wednesday, she and forward OG Anunoby posted a FaceTime call on Instagram teasing today’s performance.

“This is my city, and the city’s on fire,” she told him. “There’s so much love in the city. We’re proud of you.”

The ticker-tape procession traveled from Battery Park through the Canyon of Heroes to City Hall, where Mayor Zohran Mamdani presented Finals MVP Jalen Brunson and the rest of the team with the keys to the city.

The Knicks defeated the San Antonio Spurs in five games for their first NBA championship in 53 years.
