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 as 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.
