Here's a preview of Saturday night's first Splash! 2014 heat, with a look at the celebs in training.
Those taking part in the first heat include Diversity star Perri Kiely, who claims his dance skills don't give him as much advantage as some may expect.
“I thought I might have a bit of a head start with the flips but there is so much technique involved," he said. “It’s very difficult but I’m having so much fun.”
He'll join TOWIE's Gemma Collins, who joked: “I’m not going to lie – the training is exhausting. But I feel that at Rio in 2016, Tom might have some competition.”
TV presenter Michaela Strachan meanwhile admitted that she was out of her comfort zone in a swimsuit live on the telly.
She said: “I’m fairly happy with how I look but all the same – when you’re older, you know people will be critical of what you look like.”
Eastenders actor Ricky Groves reveals he took up the challenge to get a bit of exercising, explaining: “Acting is my trade, but it is not the most physical of jobs. So when an opportunity like this arises, you don’t hesitate to say yes.
Completing the line up of this weekend's first heat is Hollyoaks' Gemma Merna, who confessed she was already fearing a wardrobe malfunction: “I have tried a cut-out swimsuit but my boobs are going to have to be strapped in because you hit the water so hard, it could come off”.
Splash! 2014 starts this Saturday night on ITV.
