Rob Marshall knows his musicals.

With the movie adaptations of 'Chicago' and 'Nine' under his belt, and the brand spanking new Disney adaptation of Broadway legend Into the Woods in cinemas right about now, he's Tinseltown's hottest director when it comes to all things singing and dancing.

So given the chance to chat to him, we obviously quizzed him on which pop star he'd love to work with.

Brilliantly (for us, and hopefully her agent), he picked everyone's favourite Queen Monster of pop.

'Into the Woods is in UK cinemas now.'
