TV presenter Michaela Strachan, and Diversity dancer Perri Kiely progressed in Saturday's first heat, but who are the celebrities taking the plunge in heat two?
Kiely was the first contestant to make it through to the semi-final, finishing top of heat one when the judges' scores and viewers' votes were combined.
Strachan then went through after beating Gemma Collins in the splash-off. Former EastEnders actor Ricky Groves and Hollyoaks cast member Gemma Merna received the lowest combined scores in the first heat.
Tom Daley's Splash! returns to ITV next Saturday (January 11) at 7pm.
