Selina Jane Griffiths was born to the popular actress Annette Crosbie (with whom there is a strong vocal similarity) and actor Michael Griffiths and has a brother Owen, two years older, who is a sound engineer. Brought up in Kingston-upon-Thames, Selina attended the Central School of Speech and Drama in London and, upon graduation, her first professional stage role was in the Restoration comedy 'The Way of the World' alongside Barbara Flynn, with whom she would later appear in the starry television adaptation of the novel 'Cranford' . On stage she has acted with the National Theatre in Michael Frayn's 'Afterlife' and 'Noises Off' and in the West End in 'The Prime of Miss Jean Brodie' and 'The Sea'. On television she has tended to appear frequently in sitcoms, playing the prudish Janet in The Smoking Room (2004), snappish alcoholic Pauline in Benidorm (2007) and Connie, a woman who should never be allowed to sing but frequently does, in Cuckoo (2012).
