The presenter duo return with their live weekend entertainment show, beginning another seven weeks of undercover pranks, celebrity surprises and competitions. Things get under way as actor Michael Sheen steps into the role of guest announcer. Ant and Dec head to LA, where James Corden finds himself on the receiving end of one of their tricks, and Stephen Mulhern presides over Ant v Dec, in which the pair take part in a life-size game of Pac-Man. Plus, one lucky audience member plays 'Win the Ads', and Wet Wet Wet join the hosts for tonight's Singalong Live. We've missed these boyos.
