Mel C, Keith Lemon, Joey Essex and Peter Andre are among the stars joining Ant and Dec on their Saturday Night Takeaway tour.
The celebs will be taking the role of guest announcers at the live arena shows, Takeaway On Tour.
Chris Moyles, Kian Egan, Paddy McGuinness, Stephen Mulhern, Nicky Byrne, Eamonn Holmes and Vernon Kay are also on board.
Former Pussycat Doll Ashley Roberts has previously been confirmed as the host of the Ant Versus Dec segment on the tour dates, while Irish dance group Riverdance will also perform.
Blue have been booked as house band.
The duo said: "Takeaway is the one show that people always tell us they'd love to be in the audience for, so we've decided to take the show to them! Just like the TV show the audience will have a chance of winning some fantastic prizes as well as being an essential part of the show.
"It's been an ambition of ours for a long time to go on tour and we can't wait to hit the road!"
