Here's a first look at the stars of BBC One's Let It Shine ahead of the series' premiere this weekend.
The new BBC One talent series follows similar previous musicals series with Andrew Lloyd Webber, such as Any Dream Will Do and Over the Rainbow.
Fronted by Gary Barlow, Let It Shine will follow the hunt for singers to perform in a new stage musical based on the songs of Gary's band Take That.
The winners will perform in the production when it hits the stage in the West End.
And for the first round of auditions, they'll also be joined by guest judge, West End singer and star of Glee Amber Riley.
Gary said earlier this year: “Dannii, Martin and Amber all bring so much to this panel with the breadth of experience in music, acting, stage and TV. I can’t wait to get started – it’s going to be epic!”
In the audition rounds, the contestants must sing to impress the panel and make it through to callbacks.
Let It Shine will start on TV on BBC One on Saturday, January 7 at 7PM with the first auditions.
