The music stars' home, known as Fleur de Lys ("Lilly Flower" in French), was built by Texas billionaire David Saperstein in the 1990s. Saperstein lost the house, listed by Forbes Magazine as one of the most expensive in the United States, to his wife in a 2006 divorce and she promptly put the mega-mansion up for sale at a pricetag of $125 million.

There's no word on whether Carey and Cannon paid that full amount, but whatever they paid, they sure got a lot of bang for their buck.

The 15-bedroom, 41,000-square-foot French limestone mansion features Italian marble walls, gold-embossed leather wall coverings, gold-leaf crown moldings, a ballroom, a library, two kitchens and a 50-seat screening room. Perfect for those at-home viewings of "Glitter."

There's also a three-bedroom manager's house, staff quarters for 10, a nine-car garage and even a private jogging track.

Impressive, but can they fly right up to their front door? Our next celebrity homeowner can ...

John Travolta jet runway house

No. 2: John Travolta and Kelly Preston - Ocala, Florida

We've all been there. You had a rough day at work. Maybe your boss yelled at you, and, to top it all off, traffic was bad on the way home. But then you pull into the driveway at home and everything's all right.

Of course, if you're actor/aviation fanboy John Travolta, that driveway leading up to your home might be a runway and your commuter vehicle a private jet.

Travolta's house in Ocala, Fla., about 50 miles northwest of Orlando, is situated just off a main airstrip in the exclusive fly-in community of Jumbolair. The 6,400 square foot, $2.5 million home resembling a mini air-control tower is designed so the actor's Gulfstream and Boeing 707B can taxi right up to two outbuildings connected to the house.

Convenient if, you know, he gets a hankering for a Royale with Cheese in the middle of the night.

Travolta has called the pilot-friendly neighborhood home since 2003, after his neighbors in another fly-in community in Daytona, Fla., sued him over what they said was excessive noise from his private jets.

Last up, the house that television bought ...

The Manor Candy Spelling's mansion

No. 1: Candy Spelling - Los Angeles, California

When you have as much money as Aaron Spelling, the late producer of shows such as "Charlie's Angels," "Dynasty" and "Beverly Hills, 90210," you need a home that reflects that wealth, right?

Thus, "The Manor," a 56,500 square-foot, 123-room estate built by Spelling in 1988 after knocking down Bing Crosby's old home in the exclusive Holmby Hills area of Los Angeles.

The largest home in Los Angeles County, which given its rich and famous residents is saying something, sports a bowling alley, a single room devoted entirely to gift wrapping, an entire floor devoted to closets and wife Candy Spelling's wardrobe, a screening room, four two-car garages, a tennis court and a pool. The parking lot accommodates 100 vehicles, and there are also 16 carports.

Spelling actually died in the mansion in June 2006. The house, which cost $12 million to build, was put on the market by Candy Spelling in 2009 with an asking price of $150 million. It eventually sold, at a reduced price of $85 million, to Petra Ecclestone, daughter of Formula 1 racing mogul Bernie Ecclestone, in July 2011.
