Bruno Mars’ talented teenage nephews, Nyjah Music and Zyah Rhythm, are wasting no time building on their breakout America’s Got Talent moment.

Just days after stunning the judges with their original song “Heartbeat,” the Hawaiian brothers have officially released the song’s music video, giving fans a fresh new version of the track that many are already calling a career-defining release.

The new video arrives after the duo, ages 16 and 15, earned four unanimous yes votes during their AGT audition. Performing their original song instead of a cover, the brothers instantly stood out from the crowd and impressed the judges with their polished harmonies, confident stage presence, and mature songwriting.

Howie Mandel compared their sound to former AGT winner Grace VanderWaal, while Sofia Vergara praised the performance as “amazing.” The comparison carried special meaning for the brothers, who have previously revealed that watching VanderWaal’s audition years ago helped inspire them to chase their own AGT dream.

Now, with the official music video for “Heartbeat” released, fans are hearing a refreshed arrangement that showcases the duo’s signature vocal blend even more clearly. Directed by Mathieu Bitton and Gabriel Caswall, with Tahiti Hernandez serving as co-director, the video places the spotlight squarely on the brothers’ natural chemistry and musical talent.

Viewers who first discovered Nyjah and Zyah through AGT have continued to flood social media with praise. Many have described the song as radio-ready, highlighting the brothers’ smooth harmonies and emotional delivery. Some fans have even suggested that “Heartbeat” sounds like the kind of song that could become a wedding favorite, while others believe the performance was worthy of a Golden Buzzer.

What makes their rise even more remarkable is how little attention they have drawn to their famous family connection. Although they are the nephews of Grammy-winning superstar Bruno Mars, whose real name is Peter Gene Hernandez, Nyjah and Zyah never mentioned him during their audition. Instead, they chose to let their music speak for itself.

Behind the scenes, music has always been part of their family story. Their mother, Tahiti Hernandez-Kemper, comes from the same musical family that produced Bruno Mars, and the brothers have often spoken about singing karaoke with their grandmother as children. According to Zyah, those early family moments helped spark their love for music and performance.

Long before AGT, the brothers built a loyal following online through viral performances of Hawaiian songs, classic R&B tracks, and emotional ballads. Their growing popularity eventually led to a major opportunity when they recorded a version of Elvis Presley’s “Burning Love” for Disney’s 2025 live-action remake of Lilo & Stitch, a project produced by their famous uncle.

With “Heartbeat” now reaching an even larger audience through its official music video, many fans believe this could be the breakthrough moment that launches the brothers into mainstream success. Their combination of natural talent, strong songwriting, humble personalities, and undeniable family musical roots has already made them one of the most talked-about acts of the season.

For Nyjah and Zyah, America’s Got Talent may have introduced them to the nation, but the release of “Heartbeat” is proving they are ready for a much bigger stage.
