The summer heat in New York City isn’t the only thing scorching at this year’s US Open.
When the action kicks off at the USTA Billie Jean King National Tennis Center in Queens on Sunday, August 24, some couples — and some rumored romances — will hit the court in search of the 2025 titles in the men’s and women’s singles’ tournaments.
The relationship statuses at this year’s Open run the gamut: from a newly-engaged couple and a married duo to one buzzy rumored relationship between two of tennis’ most popular names.

Ukrainian tennis player Marta Kostyuk, who Boulter will play in the first round of the US Open on Sunday, commented, “YESSSSS!!! So happy for youuuu 
.”
De Minaur recently joked that the couple’s upcoming wedding is keeping him focused in the heat of battle.
“When I’m out there on court and you see me so stressed out, I’m just thinking of the wedding budget,” De Minaur told Eurosport at the 2025 Australian Open. “And that’s why I’m like, ‘I need to win more money, I need to win more matches.’ That’s all that goes through my head.”
Gael Monfils and Elina Svitolina
Monfils, 38, and Svitolina, 30, got married in July 2021 in Geneva, Switzerland, one year after Monfils proposed in the same scenic location.
“Mrs & Mr Monfils ,” he shared via Instagram, showing off the couple’s matching lavender ensembles both designed by the late Virgil Abloh.
In her own Instagram post after the big event, Svitolina called it “the best day of my life.”

“Every moment spent by your side reminds me how lucky I am to have you,” Monfils wrote via X to celebrate Skaï’s first birthday. “Your smile, your laughter and even your tears gave a unique color to my daily life. You have truly enlightened and transformed my life. For you, my little pearl, I wish all the happiness imaginable and all the wonders that life has to offer.”
Carlos Alcaraz and Emma Raducanu
Alcaraz, 22, and Raducanu, 22, have been the subject of relationship rumors for months — which have already followed them to New York.
The Spaniard superstar and the 2021 US Open champion teamed up for the mixed doubles’ tournament.
While the duo ultimately lost in the first round to Jessica Pegula and Jack Draper, their playful banter on court did not go unnoticed.
“Am I watching the start of a love story?” one tennis fan wrote via X.
For the time being, Raducanu has downplayed the Alcaraz dating rumors.
“We’re just good friends,” she said during her pre-Wimbledon press conference in June.

Raducanu has revealed it was Alcaraz who approached her about playing mixed doubles together.
“He asked me earlier on in the year and I was very surprised and honored and obviously excited,” she told the BBC in June. “I just went through the formality of asking my coach. But of course I was going to say yes.”
When asked about all of the conversation about her and Alcaraz, Raducanu laughed and said, “I’m glad the internet is having fun and we’re providing some entertainment for everyone.”
Jannik Sinner and Emma Navarro
After Sinner, the No. 1 player in the world, broke up with tennis player Anna Kalinskaya, there’s been some speculation he’s moved on with American tennis star Emma Navarro.
Sinner, 24, confirmed his breakup from Kalinskaya, 26, in May, telling reporters, “I’m not in a relationship.”
The Italian tennis player first revealed he and Kalinskaya were dating in May 2024.
During the Cincinnati Open earlier this month, a commentator attempted to concoct a love triangle between all three parties.
“Probably know that Kalinskaya ended her relationship with Jannik Sinner earlier this year,” the announcer said. “I noticed the other day that Sinner was out, hitting with Emma Navarro here in Cincinnati. Don’t know if that means anything, likely nothing. But, it makes you raise an eyebrow.”
Sinner and Navarro, 24, were supposed to play mixed doubles together at the 2025 US Open, but Sinner was forced to withdraw.
“He was begging me to play,” Navarro joked in July. “He was saying, ‘I heard about your volleys and your doubles skills. Please, please, will you play with me?’ I said, ‘Yeah, sure, I guess I’ll play with you. You’re not the best player, but I’ll make an exception and try to get a better partner next year.’”
However, Navarro later withdrew from the mixed doubles tournament in favor of playing singles at the Monterrey Open. Sinner, meanwhile, withdrew from the mixed doubles tournament with his new partner, Katerina Siniakova, after he became ill at the Cincinnati Open.
Despite some chatter to the contrary, Sinner and Navarro have not indicated that they are anything more than friends.
