Gemma Merna, Danielle O'Hara lined up for Splash!

Hollyoaks star Gemma Merna and model Danielle O'Hara are among those who will be taking to the diving board when Splash! returns for a second series in January.

According to The Sun Danielle has been seen practising her dive moves at a pool alongside Gemma, sparking speculation the pair will be joining Tom Daley on the ITV show.

Daybreak presenter Anna Williamson and Gadget Show co-host Pollyanna Woodboard are also among those rumoured to have signed up for the show, along with TOWIE star Gemma Collins.

A source told the paper: "We've aimed to bag the sexiest line-up of any telly show ever."

Splash" was a surprise hit when it made its debut last January, regularly pulling in around 6m viewers per show.

That series was won by Eddie 'The Eagle' Edwards, with other contestants including Joey Essex - currently the favourite to win I'm A Celebrity.
