Félix Auger-Aliassime Wife: Who Is Nina Aliassime and How Did Their Love Story Begin?

Félix Auger-Aliassime has built his name as one of Canada’s leading tennis players, but away from the court, one person has been beside him for much of his rise through professional tennis. His wife, Nina Aliassime, formerly Nina Ghaibi, has shared that journey with him since they were both teenagers.

The couple met in Miami in March 2019 when they were just 18. What began as a young relationship eventually grew alongside Félix’s increasingly demanding tennis career and Nina’s own involvement in competitive equestrian sport. After getting engaged in 2024, they married on September 20, 2025, during an elegant celebration in Marrakesh, Morocco.

Their story is more than a typical athlete relationship. Nina understands competitive sport herself, has her own multicultural family background and has become a familiar face in Félix’s player box at tournaments around the world.

Who Is Félix Auger-Aliassime’s Wife?

Félix Auger-Aliassime’s wife is Nina Aliassime, née Ghaibi. She was born on June 19, 2000, in the United States and comes from a family with Croatian and Moroccan roots.

Nina’s mother is Croatian, while her father, Karim Ghaibi, is Moroccan. Her multicultural upbringing has remained an important part of her identity, something that was beautifully reflected when she and Félix chose Morocco for their wedding.

She is also connected to professional tennis through her family. Nina is a cousin of professional tennis player Ajla Tomljanović. The pair have been seen together publicly and also appeared in the tennis documentary series Break Point.

Despite being married to a globally recognized tennis player, Nina has a sporting identity of her own.

Nina Aliassime Is a Competitive Equestrian

Nina’s main sporting passion is not tennis but horses.

She has competed internationally in show jumping and represents Morocco in equestrian competition. Her involvement with horses stretches back years and is much more than a casual hobby.

Her father, Karim, also has a strong connection with equestrian sport, making horses part of the wider Ghaibi family story.

Nina has shared glimpses of her training and time at stables over the years. Her experience as a competitive athlete may also explain why she understands the pressure and discipline involved in Félix’s career.

Professional sport often requires travel, long periods away from home and constant focus. Having a partner who understands those demands from personal experience can make a difference.

Nina is also known as an animal lover outside the competitive side of riding. Her Pomeranian, Timmy, has appeared alongside her during travels and everyday moments.

How Félix and Nina Met

Félix and Nina’s relationship began long before marriage was on the horizon.

They first met in Miami in March 2019. Both were only 18 at the time, meaning much of their adult lives have unfolded alongside each other.

Félix was already making significant progress in professional tennis, while Nina was developing her own interests and sporting career.

Their relationship gradually became more visible as Félix climbed the ATP rankings. Nina started appearing at tournaments and major events with him, but the couple still maintained a fairly private approach to their personal life.

They attended the Met Gala together in 2021 and were also photographed at other major sporting and entertainment events.

For Félix, however, Nina’s importance appears to go far beyond having someone beside him at public appearances.

He has described her as someone who understands the unusual life that comes with professional tennis. She listens, offers advice and provides support whether his concerns involve tennis or something completely unrelated.

More importantly, Félix has described Nina as his best friend.

Félix Proposed With a Letter From Their Early Romance

After roughly five years together, Félix proposed to Nina during a trip to the Seychelles in November 2024.

There was a particularly personal detail behind the engagement.

Only about two months after they started dating in 2019, Félix had written Nina a letter. He kept it hidden for years and eventually used it as part of his proposal.

The letter gave the engagement a connection to the very beginning of their relationship rather than making the proposal simply about an expensive destination or engagement ring.

When the couple announced their engagement publicly, congratulations quickly arrived from across the tennis world.

Players and friends celebrated the news, showing just how familiar Nina had become within Félix’s professional circle after years of accompanying him through his career.

Less than a year later, they were ready for the next chapter.

Their Marrakech Wedding

Félix Auger-Aliassime and Nina Ghaibi married on September 20, 2025, at the Selman Marrakech hotel in Marrakesh, Morocco.

Around 120 guests attended the celebration.

Morocco was a meaningful choice because of Nina’s family heritage, and the wedding blended different cultural traditions rather than following only one format.

The celebrations included both Christian and traditional Moroccan elements, reflecting the backgrounds of the bride and groom.

Nina played a major role in planning the wedding and its overall design. The result was an elegant celebration that still felt connected to the couple’s families and personal history.

Fashion was another major part of the occasion.

Nina wore a Vera Wang bridal gown, while Félix chose a custom Dior suit. Their wedding later attracted considerable attention beyond the tennis world and was featured in major fashion coverage.

For a couple who met at 18, the Marrakesh celebration marked the culmination of more than six years of growing up together.

Nina Remains Part of Félix’s Tennis Journey

Marriage has not changed Nina’s familiar place within Félix’s tennis career.

Fans regularly see her sitting in his player box, following matches closely and supporting him through the inevitable highs and lows of a professional season.

Her role became particularly noticeable during 2026 as changes took place around Félix’s coaching setup. With his professional team evolving, Nina and Félix’s father, Sam, became important figures traveling alongside him.

Nina’s support is not limited to encouragement from the stands. Félix has previously said she understands what he experiences as a professional athlete and can offer useful advice.

That makes their dynamic slightly different from one where only one partner understands elite competition.

Both know what it means to train, compete and deal with expectations, even though their sports are completely different.

A Relationship That Grew Alongside His Career

Félix was still in the early stages of becoming a major ATP name when he met Nina.

Since then, she has watched him experience breakthrough tournaments, difficult injuries, major victories and the pressures that come with expectations at the highest level of tennis.

By late 2025, Félix had climbed to a career-high world ranking of No. 5. His achievements also included a bronze medal in mixed doubles at the Paris Olympics and a growing collection of ATP singles titles.

His career continued progressing after his marriage, including another title in Montpellier in 2026 that strengthened his place in Canadian men’s tennis history.

Nina has been present for much of that journey, but she has never needed tennis to define her own identity.

Her equestrian background, family heritage and personal interests have allowed her to build a life that exists alongside Félix’s career rather than entirely inside it.

Félix and Nina Have Grown Up Together

Perhaps the most interesting part of Félix Auger-Aliassime and Nina’s relationship is how young they were when everything started.

They met at 18, before either knew exactly what the next several years would bring. Félix’s tennis career became increasingly global, requiring constant travel and intense competition, while Nina continued pursuing her own path.

They stayed together through those changes, became engaged in the Seychelles and eventually chose Morocco as the place to begin married life.

Today, Nina is not simply the woman frequently seen watching Félix from his player box. She is his wife, longtime friend and fellow athlete who has been beside him through much of his professional journey.

Their September 2025 wedding gave their relationship a new title, but the foundation had already been built over years. From two 18-year-olds meeting in Miami to husband and wife celebrating with family and friends in Marrakesh, Félix and Nina’s relationship has grown alongside the lives and careers they were building for themselves.
