Jay-Z may be a Brooklyn native, but he was seen showin' love to the Boston Celtics after their wild comeback win over the Warriors -- dapping up Jayson Tatum after the game.
If you missed Game 1 of the NBA Finals on Thursday, the Celtics were down 12 points by the end of the 3rd quarter against Golden State ... but Tatum and the C's went off in the 4th and outscored the Warriors 40-16 -- pulling off an upset win, 120-108.
The Celtics did it all right on the Warriors' homecourt -- and hip-hop legend Jay-Z was front and center to watch the epic win at the Chase Center.
