Michael Bublé is the star in the Guest Announcer Booth and he'll also be taking part in the End of the Show Show, while Ashley is in charge of setting the challenges in Ant versus Dec.
The boys undertake one of their most difficult Undercovers to date when they try to trick friend Holly Willoughby on the set of Surprise, Surprise, and Eamonn and Ruth take part in I'm A Celebrity Get Out…Of Me Ear!
Little Ant and Dec are back rubbing shoulders with the A listers, and finally one lucky studio audience member will get the chance to win the ads.
Ant & Dec's Saturday Night Takeaway, ITV, 7pm
