Early life and career
Demetriou was born in Cyprus,[1] and lived in Putney in south-west London throughout her primary school years at Brandlehow Primary School; she subsequently attended Chailey Secondary School and later Imberhorne School.
She is best known for her role as Matilda in the musical of the same name, for which she received the 2012 Laurence Olivier Award for Best Actress in a Musical.[2][3]
She made her professional stage debut in 2009 playing Gretl in the Sound of Music, and has performed on stage in Enron and Les Misérables.[4]
Demetriou made her television debut in the CBBC sitcom So Awkward playing Lily Hampton. The show, which was first aired on 21 May 2015, follows three socially awkward teenage girls at school who have the problems of fitting in, annoying parents, and boys to worry about. The show ended in 2020, but since then has spanned a number of spin-off series, all of which show Lily after leaving Cranmede.
