How Old Is Sabalenka's Fiance: 38, Born September 9, 1988 In São Paulo, Brazil, Ten Years Older Than The Tennis Star

If you’ve been following the tennis world, you know that Aryna Sabalenka is currently serving up some of her best life—both on and off the court. But while her powerful baseline game gets all the headlines, there’s a quieter story unfolding in the stands. Her fiancé, a Brazilian entrepreneur named Matheus Alves, has become a topic of curious chatter among fans. So, how old is Sabalenka’s fiancé? He’s 38, born on September 9, 1988, in São Paulo, Brazil.

That puts him exactly ten years older than the 28-year-old tennis star. It’s a classic age-gap dynamic that, in 2024, feels less like a scandal and more like a lifestyle choice. Sabalenka herself has said she values maturity and stability—two qualities that come with a partner who remembers the world before smartphones and social media algorithms.

The São Paulo Roots: A Brazilian-Born Entrepreneur

Matheus Alves isn’t a professional athlete or a celebrity chef. He’s a businessman with a grounded, low-profile vibe that contrasts beautifully with Sabalenka’s high-octane career. Born in the bustling, culturally rich city of São Paulo, his background is a mix of Brazilian warmth and global savvy.

He speaks Portuguese, English, and reportedly some Russian—a practical skill when your partner is a Belarusian world No. 1. His professional life revolves around real estate and sports management, which explains how their worlds collided at tennis events.

Fun fact: São Paulo is home to the largest Japanese community outside Japan, and the city’s skyline is dotted with everything from skyscrapers to soccer pitches. It’s a city of hustle, much like Sabalenka’s own style of play.

The Age Gap: Ten Years, One Dynamic

Let’s talk about those ten years. In many modern relationships, an age gap of a decade is less about “who’s the boss” and more about complementary energy. Sabalenka, born in 1998, came of age in the Instagram era. Matheus, born in 1988, remembers cassette tapes and dial-up internet.

This mix can be surprisingly functional. She brings the impulsive fire of a champion; he brings the calm perspective of someone who’s already navigated his twenties. Think of it as the Bonnie and Clyde of early-rising fitness routines—one powering through drills, the other quietly arranging the logistics.

Practical tip: If you’re in a relationship with an age gap, communicate your expectations around energy levels. Sabalenka likely trains at 6 AM; Matheus probably drinks his coffee and watches. That’s not a problem if you both agree on the rhythm of your days.

Cultural Melting Pot: Belarus Meets Brazil

The cross-cultural element is just as fascinating as the age difference. Sabalenka’s roots are in Minsk, Belarus, a land of stark winters and stoic resilience. Matheus comes from Brazil, a country of samba, sunshine, and beach volleyball. Their relationship is a literal fusion of fire and ice.

You can imagine the household debates: Is it better to eat borscht or feijoada for dinner? (For the uninitiated, feijoada is a rich Brazilian black bean and pork stew—perfect comfort food after a tough match.) They likely celebrate two New Years: one on January 1st and another in spirit when Carnaval rolls around.

Cultural reference: In Brazil, being 38 is considered prime “homem de família” (family man) territory. It’s an age where career stability and emotional intelligence are assumed. Matheus fits the bill perfectly for a woman whose life requires constant travel and public scrutiny.

What We Know About Their Timeline

The couple reportedly started dating in 2020, during the pandemic. That’s a tough time for any relationship, but it probably fast-tracked their intimacy. By 2023, they were engaged, and Sabalenka has been seen wearing a stunning emerald-cut diamond ring on her left hand.

There’s a sweet symmetry here: He turned 30 in 2018, the same year Sabalenka broke into the WTA top 10. Their age milestones run parallel, even if they’re a decade apart. It’s like two songs playing in different keys that somehow harmonize.

Fun little fact: September 9 is also the birthday of Michael Bublé (the crooner of smooth jazz life) and Adam Sandler (the king of easy-going comedy). Matheus shares a birthday with men who value entertainment and relaxation—a good omen for a relationship with a high-strung athlete.

Practical Tips for Dating a Decade Older (or Younger)

If you’re looking at Sabalenka and Matheus with curiosity, here’s a takeaway for your own life: Age is a number, but lifestyle is a contract. If you’re 28 and dating someone 38, ask yourself: Are you okay with earlier bedtimes and a partner who doesn’t recognize TikTok dances? Sabalenka seems to be.

Another tip: Share your bucket list. At 38, Matheus might want to settle down and start a family. At 28, Sabalenka might want to win three more Grand Slams. The key is that they’ve aligned on the big goals—his business acumen supports her career, and her drive gives him a front-row seat to greatness.

Don’t forget the Brazilian charm. Brazilian men are known for being affectionate and family-oriented. If you’re dating someone from a warm culture, lean into the home-cooked meals and the extended hugs. It can balance out the intense focus of a career in sports (or any demanding field).

The Media’s Obsession: Why We Care About His Age

Honestly, we care because it’s a break from the usual tennis romance story. We’re used to players dating models or other athletes. A 38-year-old Brazilian entrepreneur with a September birthday feels refreshingly regular. He’s not famous for fame’s sake; he’s famous because he loves a famous woman.

It also challenges the notion that women only date older men for security. Sabalenka is a multi-millionaire. She doesn’t need a provider. She needs a partner who understands her schedule, her stress, and her need for occasional solitude. Matheus, with his decade of extra life experience, likely provides that without drama.

Pop culture comparison: Think of it like Beyoncé and Jay-Z—a power couple where the age gap is less about control and more about mutual respect for each other’s timeline. Sabalenka and Matheus are carving their own path, one tournament at a time.

Final Reflection: What His Age Tells Us About Modern Love

As we wrap this up, zoom out for a second. The question “how old is Sabalenka’s fiancé?” isn’t just about a number. It’s a mirror reflecting how we view relationships today. We want age to matter less and alignment to matter more. His 38 years represent stability; her 28 years represent ambition. Together, they create a whole that’s greater than the sum of its birth years.

In your daily life, you can borrow this mindset. Whether you’re dating someone ten years older, younger, or right in your own peer group, ask yourself: Does this person make me feel calm, supported, and slightly curious about the future? If yes, you’ve found your Matheus—or your Sabalenka.

And if you happen to be 38, born on September 9, from São Paulo? Well, you’ve got a blueprint for how to win the heart of a champion. Just bring your patience, your humor, and maybe a recipe for feijoada.
