Series 7, Show 15 (Results) - S7.E17

Three couples danced their hearts out in a bid to make it to the final, but one must now leave the competition. Someone's dancing dream will be over for good, but who will leave the competition empty handed?

Whilst they wait for the all important results there's a jaw dropping performance from the World Showdance Champions, plus the cast of Hairspray perform.

There's also music from Lily Allen.
