By Introduction
Tahiti Hernandez is widely recognized as one of Bruno Mars’s sisters, but that description covers only one part of her story. Raised in Hawaii in a family where singing, dancing, instruments, and live performance were part of everyday life, she developed her own connection to music long before her brother became an international star. She later joined her sisters in The Lylas, released music, and appeared in a reality series showing the rewards and pressures of chasing a career in Los Angeles.
Her life also moved in directions that many celebrity profiles overlook. She became a mother, built a family with professional surfer Billy Kemper, and developed a career in health and fitness on Oahu’s North Shore. Today, her public identity combines music, motherhood, entrepreneurship, and Hawaiian community life. This profile explains her documented background, career milestones, family relationships, and present work while separating reliable facts from unsupported online claims.
Who Is Tahiti Hernandez?
Tahiti Hernandez, also known as Tahiti Hernandez Kemper, is a Hawaii-born singer, former reality television personality, certified fitness instructor, gym owner, wife, and mother. She became nationally known through The Lylas, the vocal group formed with Jaime Kailani, Tiara Hernandez, and Presley Hernandez. The name meant “Love You Like a Sister.”
Key facts include
- She sang and appeared on television with The Lylas.
- She grew up with Bruno Mars and drummer Eric Hernandez.
- She later moved from entertainment into fitness.
- Her exact birthday and net worth are not clearly established by reliable sources.
Early Life in a Musical Hawaiian Family
Born and raised in Hawaii, Tahiti Hernandez grew up in a large performance-oriented family. Her parents, Peter Hernandez and Bernadette Bayot Hernandez, met while working in entertainment: Peter played percussion, while Bernadette was a hula dancer. Their home included instruments, karaoke, jukeboxes, and regular family singing.
The family included
- Bruno Mars, singer, songwriter, and producer
- Eric Hernandez, drummer for the Hooligans
- Jaime, Tiara, Tahiti, and Presley, who became The Lylas
This environment taught the siblings that music involved discipline, teamwork, and audience connection, not simply natural talent.
How Childhood Shaped Her Musical Style
Tahiti’s musical education came mainly through family performance. The Hernandez children were exposed to doo-wop, 1950s pop, rhythm and blues, harmony singing, and stage entertainment. Their mother encouraged them to harmonize, while their father organized family shows.
That upbringing helped her develop
- Vocal blending and timing
- Confidence in front of audiences
- Experience working with relatives
- An understanding of performance energy
Her story shows how a creative household can work like an informal arts school. Those early lessons became useful when the sisters later tried to establish a musical identity separate from their famous brother.
Tahiti Hernandez and The Lylas
The Lylas gave Tahiti Hernandez her most visible period as a recording artist. The four women put out the single “Come Back” on their own in early 2013 and were getting ready to go to Los Angeles to work on an album and look for more opportunities.
| Member | Quality highlighted in early coverage |
| Jaime Kailani | Organizer and nurturing figure |
| Tiara Hernandez | Assertive and focused |
| Tahiti Hernandez | Comedic and peacekeeping |
| Presley Hernandez | Energetic and playful |
Their family connection brought attention, but it also created pressure. The sisters were often compared with Bruno Mars and said they still had to prove themselves as performers in their own right.
Her Role in The Lylas Reality Series
The 2013 reality series The Lylas followed the sisters as they moved from Hawaii to Los Angeles to work on music. The show covered career pressure, disagreements with management, rehearsals, live performances, and the challenge of turning sibling relationships into business partnerships.
Tahiti’s storyline focused strongly on motherhood. She had to weigh professional opportunities against being away from her children.
The series highlighted
- The uncertainty faced by emerging artists
- The strain of relocating for a career
- The difficulty of mixing family and business
- Tahiti’s effort to balance ambition and parenting
Loss, Family Bonds, and Resilience
During production, the Hernandez family experienced the sudden death of Bernadette Hernandez in June 2013. Later episodes showed the sisters grieving and struggling to continue singing after losing their mother, who had been a major musical and emotional influence.
The tragedy changed the meaning of their career journey. Continuing was no longer only about contracts or recognition; it also involved grief, memory, and family unity. Tahiti had described the sisters as close despite ordinary arguments, and that bond became especially important when private loss unfolded under public attention.
Marriage to Billy Kemper and Motherhood
Tahiti Hernandez is married to Billy Kemper, a professional big-wave surfer from Hawaii. They have four sons and are closely connected with life on Oahu’s North Shore. Her official gym biography also identifies her as a Hawaii native and mother of four.

Her sons Nyjah and Zyah perform as Nyjah Music and Zyah Rhythm. They contributed to “Burning Love” for the 2025 live-action Lilo & Stitch and auditioned for America’s Got Talent season 21 in June 2026.
From Entertainment to Fitness Entrepreneurship
After moving away from entertainment as her main profession, Tahiti Hernandez became a certified fitness instructor and co-founded Uproar Training Facility with Billy Kemper. The business focuses on strength, agility, physical health, and mental well-being for different fitness levels.
Programs associated with the gym include
- Yoga and spin
- Circuit training
- Boxing
- Adaptable low- and high-impact exercise
- Wellness and recovery retreats
A 2023 profile described her use of music, energy, and fun to make workouts welcoming. Her fitness career also connects naturally with her stage background: rhythm, motivation, group participation, and performance energy all translate well into coaching.
Building an Identity Beyond Bruno Mars
Tahiti’s journey shows why a person should not be defined only by a famous relative. Her public life has moved through three clear stages:
- Family performer: Learning music and stagecraft in Hawaii.
- Group artist: Pursuing music and television with The Lylas.
- Fitness entrepreneur: Using leadership and energy to support community wellness.
Her career change should not be viewed as a failure. People often redirect their abilities as responsibilities and interests change. Tahiti Hernandez appears to have moved toward work offering family stability, local impact, and direct relationships with clients.
Public Presence and Lasting Influence
As of July 2026, Tahiti Hernandez maintains a selective public presence rather than seeking constant mainstream celebrity attention. Recent coverage identifies her mainly as a fitness coach and gym owner, while renewed interest in her family has come through her sons’ music.
Her lasting influence includes
- Helping The Lylas build a platform of their own
- Showing the challenges of motherhood in entertainment
- Turning performance skills into fitness leadership
- Continuing a multigenerational musical tradition
- Building a public life rooted in Hawaii
Claims about her private wealth or exact personal details should be treated cautiously unless supported by direct, reputable sources.
