The new show will see Tom attempt to teach a group of celebrities how to take the plunge, before they take to the diving board live on primetime TV to demonstrate what they've learned.
It is up to the judges to score the performances, with viewers voting for their favourite dives.
Each week, the star with the most public support will automatically go through to the final. The judges will then choose between the next two top vote-getters after they go head-to-head in a 'Splash-off'.
Leon is a former diver who won his silver medal at the 2004 Athens Olympics in the men’s synchronised 10 metre platform, with partner Peter Waterford. He retired from the sport in May 2008, and is now a BBC commentator and one of Tom's mentors.
Andy established the UK's first competitive diving programme in 1988, and has gone on to become the coach for both Tom Daley and Team GB.
Jo is a bit of a surprise addition to the line-up, and has no doubt been chosen bring a bit of hilarity to the proceedings. However, she has dabbled in diving before, being coached by Tom's former partner Blake Aldridge in Dave show 'Jo Brand's Big Splash' in 2011.
Splash! - which will be hosted by Vernon Kay and Gabby Logan - debuts this Saturday at 7.15pm on ITV1.
