As Canadian songbird Celine Dion’s five-year gig in Las Vegas ended over the weekend, workers in Jupiter Island were working overtime to make sure her new digs on tony Jupiter Island would be finished on time for her planned move late next summer.

Blueprints filed with the town recently show the 9,800-square-foot, six-bedroom Key West-style beachhome will have 40 first-floor windows facing the ocean and a rare feature in coastal Florida: an honest-to-goodness basement with space for four cars, a wine cellar and giant closets.

The price tag is close to $20 million, including $12.5 million for the 3.7 acres in the dunes, $3.2 for the main cross-shaped home, plus $1.1 for a four-room guesthouse, $600,000 for a cabana and two Olympic-sized pools.

Best Page 2.1 can tell, however, is that the clothesline Dion said she would use to dry her household’s clothes hasn’t been put up just yet.

The French-speaking chanteuse of the Titanic soundtrack isn’t commenting about the construction. But she recently said she’s planning to live on the island full-time and already contacted private schools for son Rene-Charles, 7.

It’s the second time Dion and hubby Rene Angelil will be living in these parts. They once owned a place on the other side of the Intracoastal, in the nearby Admirals Cove in Jupiter.

The golf-crazy singer, meanwhile, will be living up-the-street from Tiger Woods, whose home should be ready a year later.
