**MADRID** — As the world of professional tennis pauses to celebrate the 28th birthday of its reigning queen, the spotlight has shifted from the baseline to the bright lights of celebrity romance. **Aryna Sabalenka**, the WTA World No. 1, marked her special day on May 5, 2026, not just with her signature power on the court, but with a grand romantic gesture from her fiancé, **Georgios Frangulis**, that has set the internet ablaze.
A Diamond-Studded Milestone
While the Belarusian superstar is known for her thunderous serves, it was a different kind of “ace” that dominated the conversation this week. Reports and fan speculation have surged regarding a birthday tribute from Frangulis, the Brazilian entrepreneur and founder of the global health-food giant *Oakberry*. According to sources close to the couple’s social circle, Frangulis surprised the tennis icon with a gift estimated to be worth **$3.5 million**.
This staggering figure follows the couple’s high-profile engagement in March 2026, where Sabalenka was presented with an extraordinary **12-carat oval-cut diamond ring**. At the time, the world number one playfully joked on social media that she had “requested 14 carats,” highlighting the lighthearted and resilient spirit that has endeared her to millions. The recent birthday addition—rumored to be a piece of high-end jewelry designed to complement her engagement set—serves as a glittering prelude to their upcoming nuptials.
Love in the Limelight
The relationship between Sabalenka and Frangulis has been a source of immense strength for the champion. First linked in early 2024, the pair went public in May of that year. Since then, Frangulis has become a permanent fixture in the player’s box, providing a steady emotional anchor during a period of both professional triumph and personal grief.
Fans have watched the “Power Couple” evolve from business partners—Sabalenka is a global ambassador for *Oakberry*—to soulmates. The timing of this latest extravagant gift is significant, as the couple is reportedly finalizing plans for a wedding later this year. Sabalenka hinted at the impending union earlier this season at the Brisbane International, telling a delighted crowd she was eager to change her fiancé’s “title” to something more permanent.
The Smile Heard ‘Round the World
For Sabalenka, the birthday celebrations provided a much-needed moment of joy. The 2026 season has been a grueling one; though she retains her top ranking, she has faced stiff competition from rivals like Elena Rybakina and Hailey Baptiste. A recent quarterfinal exit in Madrid left the champion frustrated, but the sight of her glowing in social media posts alongside Frangulis suggests that her off-court happiness is at an all-time high.
“Putting a smile on that face is the easy part,” a source close to Frangulis remarked. “He understands the pressure she is under and wanted this birthday to feel like a sanctuary from the noise of the tour.”
Fans and Speculation
The “3.5 million” figure has ignited a frenzy among tennis enthusiasts and fashion bloggers alike. While neither Sabalenka nor Frangulis have officially released the receipt, the sheer scale of the jewelry Sabalenka has been sporting in recent Tatler photoshoots lends weight to the rumors of a high-valuation gift.
As the tennis circuit moves toward the French Open, the “Sabalenka Wedding Watch” is officially in full effect. Whether it’s a rare gemstone or a private estate, the consensus among fans is clear: the World No. 1 has found a partner who matches her brilliance both on and off the court. For now, the champion seems content to let the fans speculate while she focuses on the two things that matter most—her upcoming marriage and her next Grand Slam title.
