Price: $125 million*
Location: Los Angeles, California

Although Mariah Carey and her ex-husband Nick Cannon never actually managed to possess this property, it is still worth mentioning for so many reasons. The property in question is Fleur de Lys, an LA megamansion built in 2002 and modeled on Versaille and even features a ballroom. It also contains a 50-seat movie theatre and staff quarters.

The original owners of the property listed the mansion at $125 million and as incredible as this 12 bedroom, 15 bathroom home is, the price wasn’t as enticing. Carey and Canon did put in an offer on the estate, however their offer was declined. The house remained on the market for several years and finally sold for $88.3 million.
