Russell Wilson, Ciara among the celebrities in the stands for Williams’s match.

Serena Williams continues to attract celebrities and politicians to her U.S. Open matches. In attendance Friday:the N.F.L. quarterback Russell Wilson and his wife, the singer Ciara; the rapper Pusha T; the actress Heidi Gardner; and the former Yankees pitcher C.C. Sabathia. Williams is facing Ajla Tomljanovic of Australia.

Anna Wintour, the editor of Vogue magazine, was spotted for the fourth time this week in Williams’s player box. (Wintour was also present for Williams’s doubles match with her sister Venus Williams on Thursday evening; the sisters lost in straight sets.) Serena Williams has described Wintour as a longtime friend, and it was in Vogue that Williams announced she would be “evolving away from tennis.”

Wintour wasn’t the only big name who has felt a magnetic pull to Arthur Ashe Stadium all week. Both the designer Vera Wang and the filmmaker Spike Leewere back in the stands on Friday night, too.

Other celebrities who have come out to show their support this week include Tiger Woods; the singers Dionne Warwick, Gladys Knight and Seal; the actors Anthony Anderson, Zendaya, La La Anthony and Rebel Wilson; the models Bella and Gigi Hadid; the Jeopardy winner Amy Schneider; the former N.B.A. players Jason Collins and Steve Nash; and the comedian Chelsea Handler.

Williams has refrained from being overtly political during her career, most recently deciding against commenting on the overturn of Roe V. Wade, but a number of politicians have been spotted at her matches, including former President Bill Clinton, Gov. Kathy Hochul and Mayor Eric Adams.
