The original Little Ant and Dec were played by James Pallister and Dylan McKenna-Redshaw. They are now 37 years old and back on a TV series called "Saturday Night Takeaway."
It will be like Ant vs Dec, but with a twist! They're not going to know what they're going to be doing every week on the show until they actually film the show live.
They've now handed the baton over to two kids who will play Little Ant and Dec. James and Dylan are still friends and say they will always be lifelong friends. They gave the new boys some advice and told them to relax and enjoy the experience.
The guys recently visited Thorney Farm while they were making a new supermarket TV advert. They will be advertising for Morrisons' Supermarkets.
