Tahiti Hernandez: The Hawaiian Singer, Fitness Leader and Mother Behind a Remarkable Family Legacy
Tahiti Hernandez is a Hawaiian singer, fitness coach, business owner, television personality and mother. She became known through The Lylas, a singing group formed with her sisters and cousin. She is also recognised as the sister of international music star Bruno Mars.
Her full married name is Tahiti Hernandez Kemper. She was born on 2 June 1987 in Hawaiʻi and was raised in a family where music, dance and performance were part of daily life. Today, she divides her time between family, fitness, business, music and community activities.
Tahiti Hernandez Early Life in Hawaiʻi
Tahiti Hernandez grew up in a large and talented family in Hawaiʻi. Her father, Peter Hernandez, was a percussionist and entertainer from Brooklyn, New York. Her mother, Bernadette San Pedro Bayot, was a singer and hula dancer who was born in Manila, Philippines. Her parents performed together in Waikīkī through a family entertainment group called The Love Notes. Their children joined the performances and learned singing, dancing and stage skills from a young age.
A Musical Household
Tahiti Hernandez grew up alongside Tiara Hernandez, Presley Hernandez, Eric Hernandez and Bruno Mars. Jaime Kailani Bayot, their cousin, was also raised with the family and became an important part of their close family circle. The children regularly practised harmonies and performed together. Their family background explains why music became a strong part of the next generation as well. Bernadette’s sudden death in 2013 deeply affected the family. Her passing was also included in the television series The Lylas, which showed the sisters dealing with grief while trying to continue their music career.
Tahiti Hernandez and The Lylas
From Family Harmonies to Professional Music
Tahiti joined Tiara, Presley and Jaime to form the female music group The Lylas. The name means “Love You Like A Sister”, reflecting the relationship between the group members. The women wanted to create their own success while facing the pressure of having Bruno Mars as their famous brother. Their goal was to prove that they had their own talent, personality and musical direction. Tahiti was known within the group for her humour and peaceful nature. A 2013 interview also described her as someone who enjoyed yoga, the beach and spending time with her children.
Music Releases
The Lylas released their first single, “Come Back”, in January 2013. The group later released “Voices” in April 2014. The sisters worked towards a debut album, but only two official singles can be firmly confirmed through major music platforms. “Voices” received additional attention because Bruno Mars helped write the song. The group’s music combined pop, R&B and family harmonies. Their songs reflected their personal experiences, relationships and determination to build a career without depending entirely on Bruno’s fame.
The Lylas Television Programme
The Lylas received a reality television programme on WE tv in 2013. The show followed the sisters as they moved from Hawaiʻi to Los Angeles to pursue their music ambitions. The programme showed recording sessions, management problems, disagreements, family responsibilities and the challenges of working with relatives. Tahiti had to balance her role as a mother with the demanding schedule of a new music career.
The series ran for one season with eight episodes. It also documented the family’s emotional response to Bernadette’s death. The experience gave viewers a closer understanding of the family’s relationships and personal struggles.
