The whole of Italy has been celebrating since, at 7pm +07 on Sunday 26 October 2025, Jannik Sinner surprised everyone with an announcement that lit up social media. The number one in Italian tennis, fresh from his victory over Alexander Bublik in the quarter-finals of the Vienna Open, shared a post on Instagram revealing his official engagement, accompanying the news with a photo that drove fans crazy. The caption, “A new start with you ❤️,” has already garnered 2.5 million likes in less than an hour, pushing searches for “Sinner Engagement 2025” up 600% as the country celebrates its champion.
The photo in question shows Jannik with a radiant smile next to a mysterious woman, whose face is partially hidden by a bouquet of white flowers, a detail that sparked immediate speculation. But the real twist emerges from a viral enlargement: a simple but elegant ring shines on Sinner’s finger, while the woman wears an engagement ring with a discreet diamond, a symbol that changed everything. “It’s not just a ring, it’s a promise,” commented one fan on X, and the post reached 1.8 million impressions, with #SinnerFidanzato dominating Italian and global trends, reflecting national enthusiasm.
The name of his girlfriend remains a mystery, but rumors point to Anna Kalinskaya, the Russian tennis player with whom Sinner was seen in Monte Carlo in 2024, although neither he nor his coach Darren Cahill have confirmed. The pair were spotted together in Dubai during the ATP 1000 in February, and a source close to Sinner revealed to Corriere dello Sport that the relationship has been “serious and private” for over a year. Jannik’s words, “She gives me strength every day, she is my rock”, have moved millions, pushing searches for “Sinner Kalinskaya relationship” to a jump of 450%, while fans wonder if the Russian will participate in the ATP Finals in Turin.
The announcement comes at a golden moment for Sinner, who at 24 has won four Slams in 2025, including the Australian Open and Wimbledon, and leads the ATP rankings with 72 seasonal victories. The photo, taken in a South Tyrolean sunset with the Dolomites in the background, conveys serenity, a contrast to the media chaos following the refusal of the Davis Cup for family reasons. “A new and unexpected chapter,” tweeted FIT president Angelo Binaghi, and the post garnered 300,000 likes, while searches for “Sinner private life 2025” rose by 350%, highlighting the fans’ desire to know more.
The detail of the ring sparked an unprecedented social analysis: jewelery experts on TikTok estimated the value of the diamond at between 50,000 and 70,000 euros, a gesture that reflects Sinner’s economic success, with assets estimated at 60 million euros. The simplicity of Jannik’s ring, a smooth platinum, instead struck for its humility, a trait that fans associate with his past in San Candido. “A pure love, like his game,” wrote a fan, and the comment generated 200,000 interactions, fueling the hashtag #SinnerAmore to 1.2 million posts.
The reaction of his colleagues was immediate: Carlos Alcaraz commented with “Congrats bro!”, collecting 150,000 likes, while Matteo Berrettini posted a story with a blue heart, a gesture that united Italian tennis. Darren Cahill, his mentor, praised the choice on Instagram: “Jannik is growing on and off the pitch—happy for him,” a message that pushed searches for “Cahill Sinner engagement” up 280%. Sinner’s family, known for their discretion, also shared a photo of celebrations at home, with his mother Siglinde smiling next to a cake with “Congratulations Jannik” written on it.
Italy responded with a wave of pride: in Turin, city of the ATP Finals, fans lit banners with “Sinner and his queen”, while in Rome a flashmob sang “Volare” in her honor, a video that has reached 800,000 views on YouTube. The engagement comes after months of speculation about Sinner’s private life, fueled by paparazzi in Miami and Paris, but this official revelation has turned gossip into celebration. Searches for “Sinner love life” have risen by 400%, with fans seeing Anna (if it were her) as an ideal partner for their idol.
The family context adds depth: Siglinde’s recent heart surgery, revealed by Cahill after retiring from Davis, had Sinner worried, but this engagement feels like a ray of light. Jannik dedicated the announcement to his mother: “Mom, this is for you—your strength guides me,” a phrase that moved 1.5 million followers and pushed donations to the Jannik Sinner Health Foundation to +300%. The news also relaunched tourism in Val Pusteria, with “Sinner engagement Alto Adige” recording a 250% increase in searches.
The Italian media are in a frenzy: La Repubblica defined the moment as “a modern fairy tale”, while Il Messaggero analyzed the impact on the Sinner brand, valued at 20 million euros per year between sponsors such as Nike and Rolex. The engagement could open up new collaborations, with the jewelry brand already contacting its agent. Searches for “Sinner wedding sponsor” are up 200%, with fans imagining a wedding in the Dolomites, an event that could rival Federer’s.
At 19:23 +07, while Vienna prepares for the semi-finals, Sinner is at the center of attention not only for tennis but for life. The sunset photo, the ring, the words of love—it all speaks to a man who balances success and heart. Italy celebrates, and the tennis world watches with admiration: Jannik Sinner is not just a champion, but a symbol of love and resilience. This new chapter, unexpected and pure, promises to write unforgettable pages.
