Jalen Brunson joins Harry Styles on stage at MSG to present residency banner

Jalen Brunson crashed Harry Styles' party at Madison Square Garden on Saturday night — and helped him make a little history.

The New York Knicks star joined Styles on stage during the 30th and final night of the singer's "Together, Together" residency at the Garden, presenting him with a commemorative banner celebrating the unprecedented 30-show run. The Garden's official account later showed the banner hanging in the rafters, congratulating Styles on the milestone.

Brunson got a hero's welcome from his home crowd, drawing uproarious "MVP" chants as he stepped on stage. He arrived wearing a hat emblazoned with the phrase "TECHNO IS MY BOYFRIEND" — a slogan Styles himself has been known to wear.

The two traded jokes when they met center stage. Styles quipped that they should note they are "almost as tall as each other," drawing a laugh from the arena. Brunson shot back: "And, yes, I will return your hat."

It was not Brunson's first appearance during the residency. The Knicks guard had attended two earlier shows in the run, earning shoutouts from Styles along the way. At one of those concerts, the singer teased the crowd: "We may or may not have the King of New York in the house tonight ... Mr. Jalen Brunson. He's just trying to have a quiet night out — not a chance. Not in this city."

The crossover moment was a fitting one for two stars who share the Garden's stage. Brunson returns to his own spotlight there on Monday, when the Knicks host the Brooklyn Nets.
