Gabby Logan and Vernon Kay are back hosting as TOWIE's Gemma Collins, Hollyoaks Gemma Merna and ex-EastEnder Ricky Groves make waves.
Presenter Michaela Strachan and Diversity dancer Perri Kiely will also take to the high boards and show off what they've learned in the first heat.
They have to impress the judges – comedienne Jo Brand, Team GB diving coach Andy Banks and ex-Olympic diver Leon Taylor - as well as the viewing public.
Who will have the guts to go up to the top of the 10 metre board and show off their skills? And who will belly flop out?
