The first Splash! semi-final will take place tonight with Diversity's Perri Kiely, TV presenter Michaela Strachan, model Danielle Lloyd and Boyzone's Keith Duffy vying for a place in the final.
The celebrities, who have been mentored by Olympian Tom Daley, will perform two dives each to impress the judging panel of diving experts Andy Banks and Leon Taylor and comedian Jo Brand.
The two celebrities who will make it through to the final will be decided by a combination of the judges' scores and results of a public vote revealed at the end of the show.
Splash! will be broadcast on ITV at 6.50pm
