Last week's partying is a distant memory, as a crippling stomach bug, a twisted ankle, wardrobe disagreements, disasters on stage, laryngitis, panic attacks and two broken down buses mean it's all drama, drama, drama.
The bands are travelling to Newcastle, Aberdeen and Liverpool and performing to over 10,000 people - and they are all nervous!
Kerry Katona in particular is struggling, and 911's Lee and B*Witched's Lindsey are finding it difficult being on the tour bus together given their marriage split.
But as always, the show must go on, and we're there to witness all the highs and lows.
