Lauren and her X Factor pals, including 2014 winner Ben Haenow and runner-up Fleur East, posed for the shot yesterday after spending the afternoon on stage.
Along with their backing dancers, other stars in the shot include boy band Stereo Kicks and fellow group Only The Young. We can also spy Paul Akister, who is joining the tour for the Manchester shows, at the top centre.
Lauren posted the picture on Twitter and told her followers: "This is gonna be a good one guys!"
'The X Factor Live Tour 2015' kicks off this Friday (13 February) in Belfast, Northern Ireland, and will travel around the UK before wrapping up in London on 21 March.
Meanwhile, earlier today we revealed that a familiar face auditioned for last year's series of The X Factor - Ibiza Weekender's Deano Baily.
Now starring in the ITV2 reality show, Deano tried his luck in front of the judges last spring...however he did NOT impress with his singing!
