Olympic gymnast, 23
Why are you doing strictly?
I was asked if I wanted to do it and straight away said yes because my mum is a big fan and my nan used to love the show. When I broke it to her she was thrilled - she'll be in the front row cheering me on every week.
What are you dreading?
The training! I was also worried that it would be awkward dancing so intimately with a girl - but once I'm in the zone it'll be OK.
Have the Olympics helped?
Performing at the Olympics was the scariest thing I have ever done - I never want that feeling ever again. Obviously all of the training and pressure I put myself through over 19 years were worth it for those 50 seconds of glory, but I'm not sure I want to put myself through that again in four years' time, so who knows about Rio. But when it comes to Strictly I'm feeling much more relaxed about it than everyone else.
Did you take a break?
I went on holiday to Marbella for two weeks and did lots of drinking and partying, but now it is back to the strict regime and training. I like that, though - it keeps me on top, it keeps me fit and healthy. Flav owns me for the next couple of months!
The pressure of having one chance to perform will be something others will struggle with, but Louis will thrive on.
