Marta Kostyuk is one of the most exciting young talents in international tennis. Born in Kyiv in 2002, she turned professional at a very young age and quickly gained attention for her fearless performances. By 2026, she has already claimed multiple WTA titles, including a major breakthrough win at the Madrid Open, signaling her rise among the sport’s elite.
While her achievements on the court are impressive, many fans are equally curious about her personal life—especially questions about her boyfriend and relationship history.
Who Was Marta Kostyuk’s Boyfriend?
Before getting married, Marta Kostyuk was in a relationship with George Kyzymenko (also known as Heorhii in some sources). He was her boyfriend before eventually becoming her husband.
Their relationship became public in 2022 when Kostyuk shared glimpses of her personal life on social media. By early 2023, she officially announced their engagement, confirming that her boyfriend had proposed.
At the time, fans were curious about the identity of her partner, as he was not a widely known public figure.
A Childhood Connection Turned Romance
One of the most interesting aspects of their relationship is how it began. Marta Kostyuk and her boyfriend first met as children at a tennis club in Ukraine.
They trained in the same environment but did not immediately form a romantic connection. Years later, they reconnected as adults, and their friendship evolved into a relationship.
This kind of long-term connection added a unique depth to their story, making it more than just a typical celebrity romance.
Engagement: A Major Turning Point
In April 2023, Marta Kostyuk surprised fans by announcing her engagement on social media. She shared a photo with her boyfriend, showing off her engagement ring and expressing happiness about this new chapter in her life.
The announcement quickly gained attention across the tennis world, with fellow players and fans congratulating the couple. It also confirmed that her relationship had become serious after only about a year of dating.
From Boyfriend to Husband
Later in 2023, the couple officially got married in a private ceremony held in Cyprus.
This means that while many people still search for “Marta Kostyuk boyfriend,” the most accurate current status is that her former boyfriend is now her husband.
Their wedding marked the transition from a relatively private relationship to a more publicly acknowledged partnership.
What We Know About George Kyzymenko
Unlike Marta Kostyuk, her boyfriend-turned-husband prefers to stay out of the spotlight. He is believed to have a background in tennis, which helped him connect with her on both a personal and professional level.
Because he maintains a low profile, there is limited detailed information about his career or public life. This has only increased curiosity among fans who want to know more about him.
Why Fans Still Search “Boyfriend”
Even though Marta Kostyuk is now married, many fans continue to search for her “boyfriend.” This happens for several reasons:
- Older articles and search results still use the term
- People are unaware that she got married in 2023
- Her relationship was kept private for a long time
As a result, the keyword remains popular even though her relationship status has changed.
A Private Relationship in a Public Career
Marta Kostyuk has always maintained a careful balance between her professional and personal life. While she occasionally shares moments with her partner, she does not reveal too many details.
This approach helps her:
- Stay focused on her tennis career
- Avoid unnecessary media attention
- Protect her personal life
In contrast to many athletes who share daily updates online, Kostyuk keeps her relationship relatively low-key.
How Her Relationship Supports Her Career
Having a supportive partner can be crucial for professional athletes. Tennis, in particular, involves constant travel, intense competition, and mental pressure.
Kostyuk’s relationship has provided stability during her rise in the sport. By 2026, she has reached new heights, including winning a WTA 1000 title and climbing the rankings.
While her boyfriend (now husband) stays out of the spotlight, he is believed to be part of her support system behind the scenes.
Her Life in 2026
In 2026, Marta Kostyuk is at one of the strongest points in her career. She continues to compete at the highest level and is considered one of Ukraine’s top players.
Her personal life remains stable, with her marriage marking a new chapter beyond her earlier “boyfriend” phase.
To answer the question clearly: Marta Kostyuk’s boyfriend was George Kyzymenko (Heorhii), whom she later married in 2023.
So while people still search for information about her boyfriend, the most up-to-date fact is that she is now married. Her relationship journey—from childhood connection to engagement and marriage—adds a meaningful personal dimension to her rising tennis career.
