Caprice - who was previously a housemate in Celebrity Big Brother in 2005 - was apparently chosen for her 'sex appeal', but is said to be concerned that she'll hurt her boobs while taking the plunge!
A source told The Sun: "She is concerned hitting the water during a dive will hurt, as if you do have large boobs it can be quite painful.
"The coaches have promised to teach her the right techniques to make sure she experiences as little discomfort as possible."
Meanwhile, Adele - who played Kelly Windsor in the rural soap - hopes that her appearance will boost her acting career, according to The Daily Star. Their insider said: "She loves the idea of learning something new and isn’t averse to celebrity reality shows."
Splash will feature a group of celebrities being coached on how to dive by Olympic bronze medallist Tom and a group of professionals.
They'll then take to the water live on ITV1 on Saturday nights, with viewers voting for their favourites.
Other names rumoured to be taking part include TOWIE's Joey Essex, Sugababe Jade Ewen and ski jumper Eddie 'The Eagle' Edwards.
The show starts next Saturday at 7.15pm on ITV1.
