Celine Dion has built a water park at her luxury mansion.

The 'My Heart Will Go On' singer has splashed out on the aquatic wonderland for herself and her family at her lavish home in Jupiter Island, Florida.

The giant-sized swimming pool includes an enormous spiral water slide and a lazy river with a slow current which takes bathers partially around the property.

Celine and her husband Rene Angeli – who have a nine-year-old son, Rene-Charles, together – bought the home for $12.5 million in 2005, and it is believed to worth $20 million now.

The water park could have another person splashing around in it soon if Celine gets her way.

The 42-year-old star recently revealed she would do anything to have another baby and has been having in vitro fertilisation (IVF) to make her dream come true.

Celine – who has been married to Rene, 68, for 15 years – said: 'I'm going to try until it works."
