Olympic bronze medallist Tom Daley will be the face of a new ITV reality show called Splash!, which will test celebrities' diving talents.
A group of famous faces will take part in a number of diving challenges in a live show each week with the help of Daley and professional coaches.
"2012 has been a wonderful year for me – an Olympic medal and double gold at the Junior World Champs!" said Daley. "What better way to round it off by becoming involved in this great new show.
"[It's] a dream come true for me, an entertainment show all about diving! I'll be helping the celebrities as they master a dangerous and exciting sport and I can't wait to get started."
The new show is based on the Dutch equivalent, widely known as Celebrity Splash!.
