That massive mansion you saw before belongs to Diddy, aka Sean Combs, aka Puff Daddy, aka the guy who changes his name more often than his socks. We digress.

Anyway, Diddy put his ginorm mansion in Alpine, N.J., on the market in July 2011, and he has yet to sell it. At just $13.5 million, we can't imagine why!

Joking aside, it's easy to see why this huge home is worth so much. It's got a tennis court, a pool with a waterfall, and a six-car garage... and that's just the outside. Inside, there are three master bedroom suites among the seven bedrooms, nine full bathrooms (one partial), an indoor squash court, a gymnasium and a movie theater.

We wonder who will buy up Diddy's multi-million-dollar home. To see more pictures of the property, visit Trulia.com.
