Sam, who won The X Factor in 2013, will take the stage in London for the first time in her career at the Lyric Theatre on 12 October.
The mum-of-three will be joined by special guests for an evening of musical theatre, with Britain's Got Talent stars Collabro, two-time Olivier Award nominee, Michael Xavier, and US musical theatre composer, Scott Alan, confirmed to take the stage.
Sam 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!"
'Sam Bailey: Live in the West End' will also feature appearances from the Les Miserables alumni, The Boys of the Barricade, and a choir from Guildford School of Acting.
After winning X Factor, Sam achieved a Number 1 Christmas hit with 'Skyscraper' and a chart-topping debut album, The Power of Love. She also enjoyed a UK tour, but parted ways with Simon Cowell's Syco record label earlier this year.
'Sam Bailey: Live in the West End' is at the Lyric Theatre, Shaftesbury Avenue on 12 October 2015. Starts 7.30pm (running time approx. 90 minutes plus interval). For tickets, please click here.
