Mamdani parties with Knicks champion Jose Alvarado on Puerto Rican Day Parade float in New York

New York City's spontaneous NBA championship celebration for the Knicks quickly devolved into chaos, with Chanley Painter reporting multiple arrests, stabbings and five school buses set on fire. The NYPD deployed riot gear and police horses to control the escalating unrest after the historic victory.

Zohran Mamdani got a taste of what it's like to be a champion on Sunday.

The New York City mayor paraded with an NBA champion in New York, less than 24 hours after his hometown Knicks won their first NBA title since 1973.

After flying overnight from San Antonio back to the Big Apple, Jose Alvarado, also a native New Yorker, took part in a local Puerto Rican Day Parade, and the mayor joined him in the fun.

Alvarado spent most of his time on the float shirtless and partying, which was totally understandable in the aftermath of a championship.

A video captured from the parade showed Alvarado rapping Jadakiss' verse from Ja Rule's 2004 hit, "New York," while Mamdani also sang some words from the throwback song that's been revitalized as a Knicks anthem.

Alvarado's Knicks teammate Jordan Clarkson was also spotted on the float.
