Early Life

Olive Gray was born Olive Grant on December 3, 1994, in London, England.

They are the eldest of four siblings in a family deeply immersed in the world of music and performance.

Their parents, David Grant and Carrie Grant, are renowned vocal coaches and singers who gained widespread fame as judges on television shows like Fame Academy and Pop Idol.

The Grants have coached some of the biggest names in music, including the Spice Girls, Take That, and numerous chart-topping artists.

Growing up in such an environment meant Olive was surrounded by creativity from a young age.

Celebrities frequently visited the family home, and music was a constant presence.

In a 2022 interview, Gray recalled how the Spice Girls would hang out in their living room during coaching sessions, a surreal childhood experience that normalized the entertainment world for them.

The family has been open about neurodiversity.

Olive was diagnosed with ADHD, dyspraxia, and dyslexia during their teenage years.

This supportive family dynamic has shaped Gray’s outlook, emphasizing acceptance and understanding.

Olive attended Queenswood School, a boarding school in Hertfordshire, before pursuing formal acting training at the prestigious Guildhall School of Music and Drama, from which they graduated in 2016.

This rigorous program honed their craft and prepared them for a professional career that would blend emotional depth with technical precision.
