Luxist reports that the porpoise-voiced warbler has made an offer on palatial Beverly Hills property Fleur de Lys, built by Texas billionaire David Saperstein. Though the amount of Carey's bid has not been disclosed, the asking price for the five-acre property is $125 million.

But that buys a lot of perks. If Carey--who according to reports is planning to move to the Los Angeles area with her husband Nick Cannon--buys the property, she'll become the proud owner of a 15-bedroom, 41,000-square-foot French limestone mansion inspired by the Vaux le Vicomte palace near Paris.

The home boasts Italian marble walls, French limestone floors, gold-embossed leather wall coverings, gold-leaf crown moldings, a ballroom, library, two kitchens and a 50-seat screening room.

Oh, and staff quarters for 10 people. Can't forget the help.

"[Carey and Cannon] like the home because there's so little that needs doing to it," says a source.

Saperstein's ex-wife, Suzanne, currently owns the home.

Hopefully the place comes with plenty of closet space. Mariah's going to need a place to store her gargantuan wardrobe and luggage collection.
