From Schoolgirl to Superstar: 15-Year-Old Sari Kumu Wows with Golden Buzzer Performance

Milton Keynes’ own Sari Kumu just went from GCSE student to global sensation—all in under 8 minutes. The 15-year-old stunned both judges and viewers with her powerhouse vocals on BR Go Talent, earning none other than Simon Cowell’s coveted Golden Buzzer.

📚 A Normal Teen with an Extraordinary Gift

Sari introduced herself with shy charm:

“My name is Sari Kumu, I’m 15 years old, and I’m in Year 11 studying for my GCSEs. I live with my mom, who’s a carer, and my dad, an HGV driver.”

Humble beginnings, sure—but nothing could prepare the audience for what was coming.

🎤 The Song That Shook the Room

When asked about her song choice, Sari confidently chose “And I Am Telling You I’m Not Going”, a notoriously difficult ballad made famous by Jennifer Hudson and Jennifer Holliday.

“It shows my vocal ability the best,” she said—before stepping into a performance that would make even Broadway proud.
