X Factor winner Sam Bailey will play the West End's Lyric Theatre for one night only on 12th October 2015 (tickets on sale from 10am on 22nd June).
Bailey will be joined by special guests to perform an evening of musical theatre. The show is produced and directed by Katie Pesskin with musical direction by Michael Riley.
Bailey said: "I can't wait to take the stage in London's incredible West End and have the chance to perform some of my favourite musical theatre numbers. It's going to be a fantastic night with a few surprises for the audience."
The singer recently made a surprise appearance at Scott Alan's concert at the St James Theatre and will make her pantomime debut this Christmas as Fairy Bowbells in Dick Whittington at the Aylesbury Waterside Theatre.
