They've conquered primetime TV, won countless awards, and this year received their OBEs, but now Ant and Dec are taking on the internet to see if they can rule supreme over YouTube!
Each week this series, the Saturday Night Takeaway YouTube channel will be home to a brand new video as the duo take on some of the world's leading vloggers.
In this first battle, Ant and Dec take on YouTuber twins Niki n Sammy in the ultimate lip-reading battle, The Whisper Challenge!
It's almost too much for Dec to handle as he's reduced to tears, quite literally. The question on everyone's lips though: just who will come out on top? Ant and Dec or our YouTubers?
Conor Maynard, Jack Maynard and Oli White feature in future videos to be rolled out across the coming weeks, all centering around games the YouTubers themselves have helped make famous and viral, including The Accent Challenge, 2 Truths 1 Lie and The Best Friends Challenge.
