The Grand Slam tournament comes to a close on Sunday.

Stars like Emma Watson and J Balvin flocked to the U.S. Open on Tuesday in New York as the Grand Slam tournament reached the quarterfinals. 

Coco Gauff scored another victory after facing off against Latvia’s Jeļena Ostapenko, while Novak Djokovic of Serbia defeated American pro Taylor Fritz.

Watson opted for a minimalist look, wearing a white double-breasted suit with pleated trousers over a black tank top.

 The actress accessorized with a thin belt, a top handle purse and open-toe flats. She completed her outfit with a chain necklace and oval-shaped sunnies.

Watson wore her brunette lob in loose waves, while her makeup included a bold red-orange lip, adding a pop of color to her ensemble.

Balvin, on the other hand, sported bright hues, wearing a monochromatic pink look. 

The singer paired a knit polo with pleated trousers, accessorizing with silver jewelry and white crocodile skin wingtips. Balvin was seated next to actress Sasha Calle at the event. Both stars were invitees of Maestro Dobel, the U.S. Open’s first official tequila sponsor.

The U.S. Open kicked off on Aug. 28 at the USTA Billie Jean King National Tennis Center in the Queens borough of New York City. The first day of the tennis tournament drew a number of celebrities, including former U.S. President Barack Obama and First Lady Michelle Obama, Vera Wang, Katie Couric and Lindsey Vonn.

Spanish pro Carlos Alcaraz and Serbia’s Novak Djokovic are expected to face off in this year’s men’s finals after a nail-biting matchup at Wimbledon in July, which saw Alcaraz take home the trophy. Meanwhile, Iga Swiatek of Poland is expected to sweep the women’s singles category.
