Saturday mornings will never be the same again, as the interactive entertainment show Saturday Mash-Up crash-lands onto CBBC and BBC Two. Over two awesome hours, presenters Yasmin Evans and Jonny Nelson bring you the freshest music, fun guests and fantastic competitions for viewers to get involved with. Each week, Jonny and Yasmin video-call a viewer to crown them as the Mash-Up Monarch. The Monarchs get to make decisions about what happens in the show, including which of the studio 'subjects' to gunge. Will the King or Queen use their power wisely?

This week, Extreme Mountain Challenge, Deadly 60 and former Strictly Come Dancing star Steve Backshall is in the studio, discussing his animal adventures, answering questions from viewers and taking part in some hare-brained games. Steve takes on the fearsome Push-Off challenge - but will he avoid a mash-up gunging? Throughout the morning, viewers can get involved in the Make Me Viral challenge - who will get the nation talking with their videos? Can you get in touch to guess how many things are in the thing? Hacker T Dog causes chaos all morning, and there is cartoon fun with Danger Mouse and a brand new episode of CBBC favourite The Next Step.

So stick with Saturday Mash-Up - the show where anything can happen... except cooking! Show less
