The star-studded crowd at Game 4 of the NBA Finals was in disbelief after the Knicks’ historic comeback from down by as many 29 to beat the Spurs 107-106 on Wednesday night at the Garden.

Comedian Jerry Seinfeld’s jaw remained dropped he stood courtside in the moments after the OG Anunoby tipped in the rebound of Jalen Brunson’s long 3-point attempt with 1.2 seconds remaining to give the Knicks their first and only lead of the night.

Grammy-winning songstress Taylor Swift hugged “Law & Order: SVU” star Mariska Hargitay — a celebrity row favorite of Brunson’s — while wearing their blue-and-orange T-shirts.

The singer was seen swinging a towel and dancing with Knicks fans while exiting the world’s most famous arena, where she’s getting married to fiancé Travis Kelce on July 3.

Comedian Larry David and tennis legend John McEnroe, both celebrity row staples, were left in sheer shock by the manner in which the Knicks took a 3-1 series lead.

New York set the record for the biggest NBA Finals comeback, according to ESPN.

The celebs weren’t the only one struggling to find the words after the final buzzer.

Brunson, when asked about the frantic final minutes by the “Inside the NBA” crew on the live ESPN broadcast, simply shook his head.
