Katie Boulter’s Heartfelt Birthday Surprise to Alex de Minaur: A Secret Proposal, Wedding Plans, and Baby Dreams Revealed

In a moment that has left tennis fans around the world stunned and swooning, British No. 1 Katie Boulter gifted her boyfriend, Australian star Alex de Minaur, an unforgettable 27th birthday present on February 17, 2026. What began as a seemingly sweet and romantic gesture quickly turned into one of the most talked-about revelations in the sport this year, when de Minaur opened a handwritten card from Boulter and read words that confirmed the couple’s future together in the most beautiful way possible.

The surprise unfolded publicly when de Minaur, still visibly emotional, shared snippets of the moment on his Instagram Stories shortly after receiving the gift. In the card, Boulter had written a deeply personal message that ended with the now-viral line: “She is the one I want to marry and now we have…” The ellipsis, it turns out, was no accident. According to de Minaur himself, who later spoke exclusively to a select group of reporters, the full sentence continued: “…decided that we will soon be getting married and we are planning to start a family next year.”

The revelation sent shockwaves through the tennis community and beyond. Fans who had followed the couple’s low-key but affectionate relationship since they first went public in mid-2023 were left speechless. Many had speculated about engagement rumors for months, especially after Boulter was spotted wearing what appeared to be a promise ring during the Australian Open in January 2026. But no one expected such an open, heartfelt declaration—and certainly not one that included concrete plans for marriage and children.

De Minaur, known for his reserved nature off the court, admitted that the message caught him completely off guard. “I was already overwhelmed by the gift itself—a custom-made watch engraved with coordinates of the court where we first met during a mixed doubles exhibition in 2022,” he said. “But when I read the card… I just froze. My heart was racing. I had to read it twice to make sure I wasn’t dreaming.”

The birthday celebration itself was intimate, held at a private residence in Sydney following de Minaur’s strong run at the inaugural Brisbane International event earlier in the month. Boulter flew in from the UK after competing in the Linz Open, where she reached the quarterfinals. Friends close to the couple described the evening as “magical but emotional,” with close family members and a handful of fellow players in attendance. When de Minaur read the card aloud to the small group, there were tears, cheers, and hugs all around.

Boulter’s message was more than just a romantic note; it was a bold statement of commitment in an era when many high-profile athletes prefer to keep personal milestones private until the last possible moment. By choosing to share the essence of the card publicly (albeit indirectly through de Minaur’s Stories), the couple signaled that they are ready to embrace this new chapter openly.

The couple first sparked dating rumors in the summer of 2023 when they were seen training together and attending events hand-in-hand. Their relationship blossomed quietly amid busy tour schedules. Boulter, 29, has often spoken about how de Minaur’s calm demeanor balances her fiery competitiveness, while de Minaur credits Boulter with helping him stay grounded during the pressures of top-10 tennis.

Their support for each other has been visible on and off the court. Boulter was courtside cheering during de Minaur’s breakthrough quarterfinal run at the 2024 US Open, and de Minaur flew to Nottingham to watch Boulter defend her title at the WTA 250 event in 2025. They have also been open about the challenges of a long-distance relationship, with both spending large parts of the year traveling between continents.

The wedding plans, according to de Minaur, are still in the early stages but very real. “We’ve talked about it for a while now,” he revealed. “We both want something small and meaningful—probably somewhere quiet, maybe back in Australia or in the English countryside where Katie grew up. We don’t want it to turn into a circus. It’s about us, our families, and the people who matter most.”

As for starting a family in 2027, de Minaur admitted the decision came after several candid conversations about balancing career ambitions with personal life goals. “Tennis has given us so much, but we both feel ready for the next phase,” he said. “We’re not rushing anything, but we’re excited about what’s ahead. Having a little one running around while we’re still playing? That would be pretty special.”

The news has sparked an outpouring of support from fellow players and fans alike. Novak Djokovic posted a simple heart emoji under de Minaur’s Story, while Emma Raducanu commented, “This is the cutest thing ever. So happy for you both!” Andy Murray, a longtime mentor figure to de Minaur, sent a private message that de Minaur later described as “typical Muzza—short but full of warmth.”

Media outlets quickly picked up the story, with headlines ranging from “Tennis Power Couple Set to Tie the Knot” to “De Minaur and Boulter Planning Baby in 2027!” Social media exploded with fan edits, montages of the couple’s sweetest moments, and even mock wedding invitations featuring tennis rackets and baby onesies.

For Boulter, the gesture was also a way of reclaiming her narrative after a challenging few years. Injuries and inconsistent form had tested her resilience, but her relationship with de Minaur has been a constant source of strength. By writing such an open letter, she showed vulnerability and confidence in equal measure—qualities that have endeared her to fans even more.

De Minaur, meanwhile, has entered 2026 with renewed motivation. Currently ranked No. 8 in the world, he has spoken openly about wanting to win his first Grand Slam title before starting a family. “This gives me even more reason to push harder,” he said. “I want to make Katie proud, and one day tell our kids that Dad gave it everything on court.”

As the tennis season heats up—with Indian Wells, Miami, and the clay-court swing on the horizon—the couple will undoubtedly face questions about wedding dates, baby names, and how they plan to juggle parenthood with elite sport. But for now, they seem content to savor the joy of the moment.

In an age when so much of athletes’ lives is scrutinized and dissected, Katie Boulter and Alex de Minaur have chosen transparency and love over secrecy. Their story is a reminder that even at the highest levels of professional sport, personal happiness remains the ultimate victory.

What began as a birthday surprise has become a beacon of hope and romance for fans everywhere. As one viral comment put it: “If love can thrive on the tour, maybe anything is possible.”
