Her backyard will go on...and on.

Celine Dion has constructed a titanic-sized water park in the backyard of her $12.5 million mansion in Jupiter Island, Fla.

New photos of the private aquatic playland show a twisty water slide, two Olympic-sized pools and a lazy river.

She can certainly afford the backyard renovations. The French-Canadian singer was paid $100 million by Caesar's Palace for her five-year "A New Day" concert series. (The Las Vegas casino even built a new 4,296-seat venue, The Colosseum at Caesars Palace, for her.)

Dion, 42, will bank $100 million more to kick off another tour at Caesar's Palace in March 2011. She'll perform 70 shows a year for three years.

According to The Palm Beach Post, the French-Canadian singer and husband Rene Angelil, 68, purchased the oceanfront Jupiter Island property in 2005.

The Grammy winner isn't the only celeb with massive digs on Jupiter Island: construction on an enormous complex for Tiger Woods began on the exclusive Floridian isle prior to his adultery scandals.

Dion and Angelil have been married for over 15 years and have a 9-year-old son, Rene-Charles.
