If you’ve been following the 2025 US Open, you’ve likely seen Alexander Bublik lighting up the courts with his huge serve, playful creativity, and signature unpredictability. On August 31, he delivered one of the tournament’s standout performances—an intense five-set victory over No. 12 seed Tommy Paul, winning 7-6(3), 6-7(1), 6-3, 6-7(5), 6-1. The match pushed him into his first-ever US Open fourth round and brought him back to his career-high ATP ranking of No. 17.
But as much as fans love the show he puts on during matches, many are equally curious about the man behind the talent—specifically, his relationship status. Is there a girlfriend? Who supports him off the court? Let’s take a closer look at Alexander Bublik’s personal life and the family that grounds him.
Who Is Alexander Bublik’s Partner Now?
Alexander Bublik isn’t dating—he’s married. His wife is Tatiyana “Tati” Bublik, a private and steady presence in his life. The two married in 2021 in Monte Carlo, Monaco, where they reside year-round alongside many elite tennis players.
Bublik revealed he was married almost casually in a Tennis Channel interview that same year, surprising fans who hadn’t seen any wedding photos or public announcements. That’s typical of him: he’s expressive and unpredictable on the court, but extremely private when it comes to the people he loves.
Tatiyana is originally from Kazakhstan, aligning with Alexander’s decision to represent Kazakhstan professionally. She keeps her Instagram private, has a very small online footprint, and rarely appears in media. Still, fans have spotted her supporting Alexander courtside at some of his biggest moments—such as his 2023 Halle Open title and his breakthrough French Open quarterfinal appearance in 2025.
Welcoming Their Son, Vasily
In August 2022, Alexander and Tatiyana became parents to their first child, a son named Vasily. Fatherhood has softened some of Bublik’s rough edges, bringing out a quieter, more reflective side. He skipped tournaments to be present for Vasily’s birth, and he has said in interviews that becoming a father made home feel “warmer” and put tennis into perspective.
He occasionally shares small, sweet glimpses of dad life, like photos of Vasily watching his matches on TV or videos of the two playing together. But he’s intentional about keeping his son out of the spotlight, explaining that he wants Vasily to grow up privately and without the pressure of public attention.
Who Is Tatiyana Bublik?
Although she maintains a low profile, a few things are known about Tatiyana. Some reports note that she has a background in economics or finance, while others claim she once modeled in Kazakhstan. None of this has been firmly verified, and Alexander himself avoids discussing her career publicly.
What is clear is that she supports her husband wholeheartedly. She has been seen in his players’ box at key events, and she occasionally joins him for formal appearances—such as when the couple walked the red carpet at the 2023 Cannes Film Festival. Fans loved their polished, elegant look, a stark contrast to Alexander’s usual quirky demeanor on court.
Tatiyana’s quiet presence and preference for privacy seem to balance out Bublik’s larger-than-life style. He has said that she provides the stability he needs amid a demanding and often chaotic tennis schedule.
A Tennis Journey Shaped by Family
Alexander Bublik was born on June 17, 1997, in Gatchina, Russia, and introduced to tennis at age two by his father, Stanislav Bublik, a longtime coach. Stanislav coached Alexander from childhood until 2019 and played a major role in shaping his powerful serve and improvisational game style.
In 2016, Bublik made the pivotal decision to represent Kazakhstan rather than Russia, citing greater support for his career from the Kazakhstan Tennis Federation. It was a turning point that ultimately allowed him to flourish on the ATP Tour and become Kazakhstan’s top-ranked men’s singles player.
Stanislav’s influence on his career runs deep—he also coached other pros, including Mikhail Kukushkin and Dmitry Popko. While Alexander now works with coach Artem Suprunov, the foundation built by his father remains evident in his style and approach.
A Career Known for Highs, Lows, and Big Personality
Bublik’s 2025 season has been one of his strongest. Entering the US Open with a 38–17 record, he has collected wins over former champion Marin Čilić and several Top 50 players. Earlier in the year, he reached his first-ever Grand Slam quarterfinal at Roland Garros. He has also earned titles on clay in Gstaad and Kitzbühel and pulled off a stunning win over world No. 1 Jannik Sinner at Halle—setting up an exciting rematch at the US Open.
He’s known for:
- a monster serve,
- flashy underhand aces,
- tweener winners,
- moments of comic brilliance…
- …and occasional controversy.
But at the heart of it all is a fiercely dedicated competitor who spends hundreds of thousands of dollars annually on training and travel to keep his team running.
Even when he slumps—as he did after the 2024 Olympics—Bublik tends to bounce back with dramatic flair, making him one of the sport’s most entertaining figures.
Why Fans Are Curious About His Love Life
Part of the fascination with Alexander Bublik’s relationship status comes from how unpredictable he is on court. Fans want to know the person who supports him behind the scenes—the one who keeps him grounded when matches swing wildly or interviews spark headlines.
Because he shares so little publicly, the fact that he’s married and a father surprises newer fans. The contrast between his playful, sometimes fiery tennis persona and his quiet family-centered life makes him even more intriguing.
(And for clarity: any unrelated searches like “Eystreem’s girlfriend” don’t apply here—Eystreem is a YouTuber and has nothing to do with Bublik!)
Looking Ahead
With a fourth-round showdown against World No. 1 Jannik Sinner on the horizon, Bublik is entering one of the biggest moments of his career. Off court, he continues building a peaceful life in Monte Carlo with Tatiyana and little Vasily, all while balancing the demands of the ATP Tour.
He may be unpredictable with a racket in hand, but one thing about Alexander Bublik is remarkably steady: his devotion to his family.
Conclusion
Alexander Bublik might be known for his big serves, trick shots, and entertaining antics, but at home, he’s a husband and father first. His marriage to Tatiyana and their life with their son, Vasily, reveal a grounded, private side that contrasts with his on-court fireworks.
As he continues carving out memorable moments in tennis, fans can appreciate that the man they see on court is supported by a loving, low-key family life that helps keep him steady—even when the matches get wild.
Whether he’s chasing aces or chasing Vasily around the house, Alexander Bublik is proving that balance is possible—even for one of tennis’ most unpredictable stars.
