At 20 Olivia is already a veteran of film, television and the stage, and has appeared in over 100 productions since the age of seven. She is the youngest of four sisters and grew up in Hounslow, London. Her first ever big role, was playing alongside Cilla Black in the 1991 production of Robin Prince of Sherwood. Since then, she has starred in five stage productions, three films and more than ten television hit shows including The Bill, Holby City and Granada TV's smash hit show, Girls in Love. The CITV show was taken from the novels of Jacqueline Wilson and Olivia was delighted to play the main character Ellie, though her new found fame is something she is still getting used to. Her mother, who runs the Saturday Drama School, called 'All Expressions', in Teddington, tried distract her from becoming an actress, but Olivia's determination to perform could not be taken away. She then began training at her mum's school when she was 11 and there gained the confidence she needed to break out into acting.
