This week it's all about the girls, as our seven Sophies take centre stage. Plus, host Zoe Ball reveals a very special surprise from Hollywood A-lister.

As ever, judges Alan Carr, Jessie Ware, Samantha Barks and Amber Riley will put the girls through their paces as they tackle their first acting workshop by recreating a famous scene from the film. And there'll be seven show-stopping performances, but When All Is Said And Done, who will be sent packing back to the UK and out of the running to be crowned Sophie in London's West End?

It's chemistry week on Mamma Mia! I Have a Dream, as judges Alan Carr, Jessie Ware, Samantha Barks and Amber Riley pair up our Sophies and Skys for the very first time. 

Sparks fly, in more ways than one, as our couples get cosy in this week's workshop where they perform the iconic love scene from the stage show, Lay All Your Love On Me.

And as ever, the local Greek audience will be treated to six show-stopping performances, but who will host Zoe Ball be consoling elimination.
