The home, which is jointly listed by Sotheby's International Realty agents Joseph Montanaro and Cristina Condon, was custom-built and designed in 2010 by Celine Dion herself.
She and her manager husband Reneé Angélil bought the lot of land in 2005 for $12.5 million and the adjacent mansion in 2008 for $7 million, The WSJ reports. They then razed to build the current spread.
The five-and-a-half-acre property has views of the Atlantic Ocean, a four-bedroom guest house, a simulated golf range, pool house, and three separate pools.
The main residence alone measures close to 10,000 square feet, with five bedrooms and a custom-designed, walk-in closet with automated rack for clothing and automated carousel for shoes.
Last year, Dion listed her home on a private island in Quebec for $29.3 million; it's still on the market.
