Who Is Tahiti Hernandez?
Tahiti Hernandez is an American woman from Hawaii. She is the sister of Bruno Mars, one of the world’s top singers. But she also has her own story to tell.
Music filled her childhood home every day. Singing and dancing were not just fun for her family. They were a way of life. This shaped who Tahiti became as an adult.
Her brother went on to become a global star. Tahiti chose a different but still busy road. She sang in a group, appeared on TV, and then found a new passion in fitness.
Fans search for her name for many reasons today. Some want to learn about Bruno Mars’ family. Others follow her gym and workout tips. A growing number now follow her sons, who are starting their own music journey.
Tahiti Hernandez’s Early Life in Hawaii
Tahiti Hernandez was born on June 2, 1987, in Honolulu, Hawaii. She was one of six children in a busy and musical home. Her family did not just love music. They performed it on real stages.
Her father, Peter Hernandez, came from Brooklyn, New York. He had Puerto Rican and Jewish roots. Her mother, Bernadette San Pedro Bayot, moved to Hawaii from the Philippines as a child.
The whole family performed together in a show called The Love Notes. This act played at the Sheraton Waikiki hotel for many years. Young Tahiti watched her parents sing and dance in front of real crowds.
This kind of upbringing taught her stage skills early. She learned rhythm, timing, and confidence as a little girl. It also built a close bond between her and her brothers and sisters, including young Bruno.
Tahiti Hernandez’s Family and Siblings
Tahiti has five siblings in total. They are Eric, Jaime, Tiara, Presley, and Bruno Mars, whose real name is Peter Gene Hernandez. All six children grew up under one musical roof.
Eric became a drummer and later joined Bruno Mars’ band, The Hooligans. This shows how deep music runs in this family. Nearly every sibling found some link to performing.
Over the years, Tahiti stayed very close to her sisters Jaime, Tiara, and Presley. The four of them later formed a group together. That bond has lasted into their adult lives.
Sadly, the family faced great pain in 2013. Their mother, Bernadette, passed away suddenly from a brain aneurysm. She was only 55 years old. This loss changed the whole family, including Tahiti.
Her Bond With Bruno Mars
Most people first hear about Tahiti Hernandez because of her brother. Bruno Mars is a Grammy-winning singer known for hits like “Uptown Funk.” Long before his fame, though, he and Tahiti shared family stages in Hawaii.
As children, the siblings performed together often. This gave them a shared history most fans never see. Their bond grew from real family shows, not from headlines or fame.
Later, Bruno still supported his sisters’ music project. He helped write a song called “Voices” for Tahiti’s group. Even as his own career grew huge, he made time to help his family.
Tahiti never chased the same level of fame as her brother. Still, she stayed close to his world. Their strong bond shows the family values both of them learned as kids.
The Lylas: Tahiti Hernandez’s Music Group
In 2013, Tahiti formed a girl group with her sisters Jaime, Tiara, and Presley. They called it The Lylas. The name stands for “Love You Like A Sister.”
The sisters released their first song, “Come Back,” on iTunes by themselves. Soon after, they put out another song called “Voices.” Their brother Bruno Mars helped write that second track.
Their music journey also became a TV show. The Lylas aired on WE tv in November 2013. Viewers watched the sisters work on music while also dealing with normal family life.
The group did not last for many years. Even so, this chapter mattered a lot. It gave Tahiti real skills in music and TV, plus proof that she could work well as part of a team.
From Music to Fitness: A Career Change
After The Lylas, Tahiti Hernandez moved into a new field. She trained to become a certified fitness instructor. This was a big change from music, but it fit her lively personality well.
Fitness gave her a fresh way to connect with people. Instead of singing on stage, she began leading workout classes. She never fully left music behind, though. Her classes often use upbeat playlists to keep the energy high.
This shift also matched island life in Hawaii. The islands have a strong culture around health and staying active outdoors. Tahiti built her new career around these same values.
Over time, fitness grew into more than a simple job. It became a real business that she now runs with her husband. This next chapter shows how she kept growing after her music years ended.
Tahiti Hernandez and Uproar Fitness
Today, most people in Hawaii know Tahiti through Uproar Fitness. She owns this gym with her husband, Billy Kemper, on the North Shore of Oahu. The gym blends strength training, cardio, and calm mindfulness together.
Her classes focus on more than just hard exercise. Music, energy, and community sit at the center of every session. Many members say her classes feel fun instead of stressful, which keeps people coming back.
Beyond regular classes, Tahiti also leads wellness retreats for a full day. These events mix workouts with recovery time, like sauna sessions and ice baths. Group meals and social time round out each retreat.
Building this gym has become a shared dream for Tahiti and Billy. In her own words, fitness is simply their life. So opening a gym together felt like the natural next step.
Tahiti Hernandez’s Husband: Billy Kemper
Tahiti is married to Billy Kemper, a professional big wave surfer from Hawaii. He has won major titles in the surfing world, including top honors in big wave events.
The couple married on November 7, 2018, in Hawaii. They knew each other for years before their wedding day. This is common for people who grow up in the same close-knit island community.
Their partnership goes beyond marriage. They also run a business together. Billy brings his athletic training background, while Tahiti brings her group fitness skills.
Fans often see the couple training side by side. They raise their kids together and support each other’s goals, both in sport and in business.
Was Tahiti Hernandez Married Before?
Yes, she was. Before Billy Kemper, Tahiti was married to Joshua Sojot, a Hawaiian DJ. The two later divorced, but they still stay connected through their kids.
That first marriage gave Tahiti two of her four sons. Reports suggest she has kept a respectful bond with her ex-husband, mainly for their children’s sake.
Blended families are common, and her story reflects that truth. She moved from her first marriage into a fresh chapter with Billy Kemper, growing her family even more.
This part of her life shows real strength. Raising kids through a divorce takes patience. Then, building a brand new marriage takes even more care. She seems to have managed both while keeping her family close.
Tahiti Hernandez’s Children
Tahiti is a proud mother of four sons. Two of them, Nyjah and Zyah, come from her first marriage. Their full names, Nyjah Music and Zyah Rhythm, show the family’s deep love for music.
With Billy Kemper, she welcomed two more boys, known as Hazey and Lion. These two have grown up close to surfing, following in their father’s footsteps.
Interestingly, her older sons Nyjah and Zyah have started making music of their own. Reports say the pair worked on a song tied to Disney’s Lilo & Stitch soundtrack in 2025. Music clearly runs through this family’s next generation too.
Meanwhile, Hazey and Lion often train in the water with their dad. Between music and surfing, all four boys carry forward different parts of their parents’ passions.
Why People Search for Tahiti Hernandez

Final Thoughts
