Meet the Lyrical Family: Who are the Siblings of Bruno Mars?

When you see Bruno Mars sliding across a stage in a silk shirt, oozing that 24-karat magic, it’s easy to think he’s some kind of musical anomaly. A one-off. But the truth is actually a lot more interesting than that. Bruno—born Peter Gene Hernandez—didn’t just stumble into a recording booth. He grew up in a household in Honolulu where music wasn't just a hobby; it was the family business. If you've ever wondered about the siblings of Bruno Mars, you're basically looking at the blueprint for his entire career.

He's one of six. Yeah, six.

Growing up in the Waikiki scene, the Hernandez kids were constantly surrounded by doo-wop, Motown, and the high-energy showmanship of their father, Peter Hernandez, and their mother, Bernadette San Pedro Bayot. It was a loud, creative, and sometimes chaotic upbringing that shaped every single one of them. While Bruno grabbed the global spotlight, his brother and four sisters have been carving out their own paths in the industry for years. They aren't just "relatives of a star." They are performers, drummers, and entrepreneurs in their own right.

The Brother Behind the Beat: Eric Hernandez

Let’s talk about Eric first. If you’ve ever watched a Bruno Mars concert, you’ve seen Eric. You just might not have realized it.

Eric Hernandez is Bruno’s older brother and the longtime drummer for The Hooligans. He’s been there since day one. While many pop stars cycle through session musicians like they’re disposable, Bruno has kept Eric at his right hand (or rather, right behind him on the riser) for the better part of two decades. It’s a chemistry you can’t really fake.

Eric didn’t just pick up the sticks because his brother got famous. He was playing in the family band, The Love Notes, back in Hawaii when they were kids. Honestly, he was a pro before Bruno was even out of elementary school. Eric’s style is that perfect mix of rock steady and incredibly flashy, which is exactly what a Bruno Mars show demands. He’s also a huge gear head and has been a massive ambassador for brands like DW Drums and Sabian cymbals.

It’s kinda cool when you think about it. The biggest pop star on the planet trusts his rhythm to his big brother. That’s a level of loyalty you rarely see in Hollywood. Eric has often mentioned in interviews that playing with Bruno isn't just about the music—it's about that shared language they developed in their living room thirty years ago. They don't even have to talk on stage; they just know where the beat is going.

The Lylas: A Sister Act with a Twist

Then we have the sisters. Press usually lumps them together under the name "The Lylas," which stands for "Love You Like A Sister." The group consists of Presley Hernandez, Jaime Kailani, Tiara Hernandez, and Tahiti Hernandez.

A few years back, they actually had their own reality show on WE tv. It was called The Lylas, and it followed their move from Hawaii to Los Angeles to try and make it as a girl group. It was raw. It showed the struggle of trying to find an identity in an industry that constantly wanted to compare them to their brother.

Breaking Down the Individual Sisters

• Jaime Kailani: She’s the eldest sister and often seen as the "mama bear" of the group. Beyond music, she’s heavily involved in philanthropy. She founded 4MamaEarth, an organization that uses entertainment and art to drive social change and environmental awareness. She’s always been more than just a singer; she’s a connector.
• Tiara Hernandez: If you’re looking for the powerhouse vocals, you’re looking at Tiara. She’s taught music and has a deep understanding of the technical side of singing. She’s often the one arranging harmonies and making sure the group sounds tight.
• Tahiti Hernandez: Tahiti is a mother and a fitness enthusiast, but she’s also got that signature Hernandez grit. On the reality show, she was often the one keeping it real when things got stressful.
• Presley Hernandez: The youngest of the sisters, Presley brings a younger energy to the dynamic. Like the rest of her siblings, she’s lived a life steeped in performance, but she’s also found her own lane in the lifestyle and fashion space.

The Lylas as a group showed that talent isn't localized to just one person in that family. They released a single called "Come Back," which showcased their ability to harmonize in a way that feels effortless. It’s that DNA thing again.

The Reality of Being a "Famous Sibling"

People often assume that having a brother like Bruno Mars means doors just fly open. In reality, it can be the opposite. The siblings of Bruno Mars have often spoken about the pressure of the "Hernandez" name. When you’re related to one of the greatest entertainers of all time, the bar is set impossibly high.

During their reality show, the sisters were very open about the fact that they didn't want to ride Bruno's coattails. They wanted to earn their own stripes. It’s a tough spot to be in. If you succeed, people say it’s because of your brother. If you fail, people say you couldn't live up to the name.

Bruno himself has stayed relatively quiet about their professional ventures, likely out of respect for their desire to be independent. But he’s always been supportive of his family behind the scenes. After the tragic passing of their mother, Bernadette, in 2013, the siblings became even tighter. You’ll often see them all together at major events or just hanging out in Hawaii, proving that the bond is much deeper than the music industry.

Why the Hernandez Family Dynamic Matters

What most people get wrong about Bruno Mars is the idea that he’s a "produced" star. He’s not. He’s a product of a family unit that functioned like a musical bootcamp.

His dad, Peter, was a Latin percussionist. His mom, Bernie, was a singer and a hula dancer. When you grow up with five siblings who all sing and play instruments, you learn how to compete. You learn how to hold your own. You learn how to entertain.

The siblings of Bruno Mars are essentially the supporting cast of his life story. Without Eric on the drums, would the live shows have that same punch? Without the sisters pushing him and being his first audience, would he have developed that specific charm? Probably not.

What You Should Know if You're Following Their Careers

If you're interested in keeping up with the Hernandez crew, don't just look at the Grammys. They are active in very different ways:

1. Follow Eric Hernandez for the technical side. If you’re a musician, Eric’s social media and clinic appearances are gold. He talks about the rigors of touring and what it takes to play at an elite level.
2. Check out Jaime’s charity work. If you care about social impact, Jaime Kailani is the one to watch. Her work with 4MamaEarth is legitimate and impactful.
3. The Lylas' music is still out there. While they haven't released a full album recently, their existing tracks are a great glimpse into the family's harmonic style.

The story of the siblings of Bruno Mars isn't a story of people living in a shadow. It’s a story of a family that collectively breathes music. They each have their own passions, their own kids, and their own businesses. But at the end of the day, they are a unit.

When you listen to a song like "Uptown Funk" or "Leave the Door Open," you’re hearing the end result of a childhood spent in a house where someone was always singing, someone was always drumming, and someone was always telling a joke.

Actionable Steps for Fans and Researchers

If you want to dive deeper into the world of the Hernandez family, here is how to do it without falling for the tabloid gossip:

• Watch 'The Lylas' Reality Show: It’s a few years old now, but it’s the most honest look at the sisters' personalities and their relationship with their brother.
• Track the Credits: Look at the liner notes of Bruno’s albums. You’ll see Eric’s name consistently. It’s a lesson in professional longevity and family loyalty.
• Support Local Hawaii Talent: The Hernandez family is a product of the Honolulu music scene. Supporting other artists from that region helps you understand the "vibe" that produced the Mars phenomenon.
• Focus on the Philanthropy: Look into the specific causes the sisters support. It gives a much better picture of who they are as people than any red carpet photo ever could.

The Hernandez family is a reminder that while one person might become the "face" of a brand, there is usually a whole lot of heart and soul standing just off-camera. They are a musical dynasty in the truest sense of the word. They’ve stayed grounded despite the insane level of fame that has hit their family, and that's probably the most impressive thing about them. They’re just a bunch of talented kids from Hawaii who happened to take over the world. Together.
