Jessica Alba and boyfriend Danny Ramirez were among a string of celebrities who attended the US Open singles finals at the Billie Jean King National Tennis Center in New York on Sunday, appearing together in the stands as the tournament concluded.

Alba, 44, who announced a separation from husband Cash Warren earlier this year, sat alongside Ramirez, 32, and was photographed chatting closely during the women's final. They joined Courteney Cox and partner Johnny McDaid, and Lindsay Lohan with her husband Bader Shammas, as well as a host of other entertainers and public figures in the VIP sections.

The day on the court ended with World No. 1 Aryna Sabalenka defeating Amanda Anisimova to capture the women's title and Spain's Carlos Alcaraz winning the men's final. The men's match took place amid visible reaction to the presence of former President Donald Trump among VIP guests.

Photographs from the event showed Alba wearing a brown leather jacket and sunglasses while Ramirez dressed casually. Cox, 61, and McDaid, 49, were photographed in coordinating dark outfits. Lohan, 38, appeared in a white Chanel dress with Shammas and their two-year-old son, Luai.

Other attendees included musicians Bruce Springsteen and Sting, actors Stanley Tucci, Ben Stiller and Michael J. Fox, models Irina Shayk and Winnie Harlow, and sisters Elle and Dakota Fanning, among others. Several celebrities were seen socializing in suites and along the clubhouse level during the match.

DailyMail.com reported that a source close to Alba said she is ready to introduce Ramirez to her three children, whom she shares with Warren: Honor, 17; Haven, 14; and Hayes, 7. The source told the outlet that Alba "is smitten" and that things between her and Ramirez "have really progressed," adding that she had initially been cautious following her separation.

Alba confirmed the split from Warren in January and the pair filed for divorce in February; the proceedings are ongoing. The Daily Mail also reported that Warren has been linked to a younger model, and that both ex-spouses are said to be accepting of each other's new relationships.

The reported Alba–Ramirez connection became public in July after the two were seen vacationing together in Cancun. Sources quoted by the Daily Mail have described the relationship as relatively new and evolving, and have said neither party has publicly outlined long-term plans.

On court, Sabalenka reinforced her top-ranking status with a decisive victory over Anisimova, while Alcaraz claimed the men's crown in a match that attracted heightened attention because of reactions to a VIP attendee. Tournament officials did not immediately comment on celebrity attendance or reactions from stands.

Photographs from the event captured moments of conversation and laughter among the celebrities as well as tense observation during pivotal points in the matches. Several attendees were seen gathering afterward in hospitality areas, and fashion choices ranged from formal dresses to casual jackets and jeans.

Representatives for Alba, Ramirez and other individuals named did not immediately respond to requests for comment. The US Open will conclude its tournament week with award ceremonies and player media commitments following the finals.
