Yasemin Kay Allen was born on July 10, 1989, in London, to English father Dudley Allen and Turkish-British actress and singer Suna Yıldızoğlu. Though ethnically not Turkish, Yasemin's connection with Turkey runs deep. Her mother's marriage to Turkish actor Kayhan Yıldızoğlu and subsequent citizenship granted Yasemin dual nationality, weaving a tapestry of cultural heritage that is 50% English and 25% Australian.
