Alex Jones returns for the second live instalment of Tumble. Under the watchful eye of Louis Smith and his fellow judges, ten celebrities present an acrobatic floor routine or brave the aerial hoop. The two celebrities with the lowest scores become the first ever to face the Vault, and at the end of the episode one celebrity leaves the competition for good. Girls Aloud's Sarah Harding, boxing champion Carl Froch and The Only Way is Essex star Lucy Mecklenburgh all feature. Plus, multi-medal-winning gymnastics legend Beth Tweddle is joined by the next generation of future Olympians in a stunning showcase performance. It's gymnastics, but not as we know it! It's time to Tumble.
