Come On In, The Waltz's Lovely!

The first pictures of Strictly Underwater have been published today. Chelsee & Pasha and Harry & Aliona have donned scuba gear to dance to the depths for a segment which will air during Sport Relief on Friday.

Chelsee told the Daily Mirror: "I wouldn't say I'm a strong swimmer and I'm not that keen on water either. I like to bath in it but that's about as far as it goes."

Harry reveals he was skeptical at first: "When I first heard about Strictly Underwater, I thought 'How is that going to work?'. I didn't quite understand what they meant and I didn't think it would work - but it does."
