Fearon attended the Sharon Harris Drama school in Wembley[3] and St Gregory's Catholic Science College in Harrow[4] before training at the Italia Conti Academy of Theatre Arts from the age of 17.

[7] Fearon appeared in a sing-a-long video for children at the age of four, A Day Full Of Songs, which was produced by Abbey Home Media in 1993.

[6][10] Fearon was part of the 2010 BBC TV talent hunt Over the Rainbow, in which Andrew Lloyd Webber searched for an actress to play Dorothy in a West End musical adaptation of The Wonderful Wizard of Oz.

She was twice saved by Lloyd Webber but, in the semi-final sing-off on 16 May 2010, lost out to Lauren Samuels after the pair performed "Another Suitcase in Another Hall" from Evita.

"[11] Fearon landed a role in a revival of the Tony Award-winning production of Smokey Joe's Cafe less than a month after being voted off Over the Rainbow.

Fearon appeared in April 2011 as Dorothy, alongside Sarah-Jane Honeywell as Glinda and Ben Hanson as the Scarecrow, in a touring production of The Wizard of Oz.

[25] She also played Diana Morales in a Tel-Aviv production of the musical A Chorus Line in October 2011,[26] and during the 2011 Christmas pantomime season appeared as Cinderella at the Sands Centre, Carlisle.
