So, who's doing what? All 15 couples are dancing so it's a jam-packed episode, with Alison and Aljaz doing a foxtrot to I Just Wanna Make Love To You, and Caroline and Pasha will be performing the tango to Blame.
Also tangoing are Scott and Joanne to Stop!, and Simon and Kristina to Sing. There's quite a few cha cha's with Judy and Anton moving to She's a Lady, Steve and Ola grooving to Treasure, and Sunetra and Brendan performing to Million Dollar Bill.
Jake and Janette are doing a salsa to Mambo No.5, and Thom and Iveta are doing one to Hot Hot Hot. Whilst Frankie and Kevin and Gregg and Aliona will perform Charlestons to the Happy Days theme and Hey Good Looking.
Back in the ballroom, we'll have a waltz from Tim and Natalie to When You Wish Upon a Star, and also Pixie and Trent to Come Away With Me, as well as Jennifer and Tristan to Natural Woman. Finally, Mark and Karen are taking on the American Smooth to I'm Yours.
