We've got another exclusive look behind the scenes of Sky Living's fashion design show Styled To Rock for you today. We're getting that little bit closer to finding out who will will and get the chance to dress Rihanna for the Wireless festival.

With 26-year-old Steve now onto a winner with a hat-trick of challenge successes behind him, it's safe to say there's an early front-runner, but there's still all to play for with six weeks to go and loads more music-based design challenges to come (including looks for The Scissor Sisters and Cheryl Cole in coming weeks).

This week, the designers will work on a look for girl group The Saturdays. This is probably the poppiest look yet for the challengers and will test their skills in sticking to the brief and dressing a band in a cohesive but interesting way. Judges Nicola Roberts, Henry Holland and Lysa Cooper will be on hand as ever to judge the final looks and decide who's leaving the competition.

Check out our gallery of exclusive behind the scenes shots above. Who's your tip to win?
