For the event, the brunette beauty styled her locks straight and wore a radiant makeup set.

Alessandra and her buddy Milan watched as Italian pro Jannik Sinner, 23, and Taylor Fritz, 26, battled for the trophy in the men’s singles final.

Jannik eventually outplayed Taylor, the number 12, 6-3, 6-4, 7-5, despite a convincing revival by the favourite in the final phase.

Later in the evening, Alessandra attended Off-White’s debut show during New York Fashion Week at Brooklyn Bridge Park.

The model showed off her fuller bust in a red lace bra and mesh top as she sat front row with friends Joan Smalls, Ayra Starr, Tinashe and Coco Jones.

Alessandra’s performance comes just days after she showed off her fitness during a game of beach volleyball in Santa Monica.

The model, who recently enjoyed a relaxing vacation in Hawaii, wore an orange swimsuit with a plunging zip-up neckline and French legs.

She wore a yellow California logo cap over her dark locks during her sporty day.

“The fashion world has evolved over the years, but there is still a lot of work to be done,” she said of the fashion world.

Ambrosio, who has modeled for Victoria’s Secret, Christian Dior, Armani, Ralph Lauren and more, would like to see some changes in the industry.

“I think it should be more inclusive and a better reflection of the amazing, diverse beauty that we see in real life.”
