One Big Super Bowl Tailgate: Celebrities Embrace New Orleans.

On Friday night, two gigantic footballs each one made of more than 400,000 sparkly gold tiles hung in the humid air and rotated like disco balls over a stage in New Orleans.

Uber was hosting a Super Bowl party before Sunday’s matchup between the Kansas City Chiefs and the Philadelphia Eagles, and drinks flowed from three bars as servers passed around shrimp Creole skewers and crawfish balls.

Solange Knowles was in a D.J. booth playing crowd favorites from so high up it was hard to see her face.

Emily Ratajkowski, the model and actress, was among the first to arrive, around 8:30 p.m., and was wearing a slinky black dress. Next came Amy Schumer, the comedian and actress, who headed to the bar where she laughed loudly with a few friends.

“I’ve had a long day,” Ms. Schumer said, waving off interviews.

The actor Jon Hamm, the designer Brooklyn Beckham, the musician Leon Bridges, the singer Tyla, and the D.J. Diplo followed, and headed into an exclusive area overlooking the space.

It was intimate but also hot. Temperatures in New Orleans were in the 80s, and the crowd was sweating.
