According to TMZ, Kim and Kanye recently dropped a huge load of money on a 14,000-square-foot mansion in an extremely private gated community area in Bel Air, CA.  In total the mansion cost $11,000,000, but even after having put out such a big chunk of money on the one mansion, they apparently plan to buy at least three more.  

According to sources claiming to be close to Kanye and Kim, the couple also want to buy mansions in New York, Miami, and possibly Paris as well.  The Kardashians have their DASH stores in New York and Miami so it would be even more convenient for them to promote their brand.
