Russell Simmons listed his NYC penthouse at 114 Liberty Street in NYC last month for $11 million, following a failed $13.5 million listing after 9/11. Back then, Diddy almost bought the house before backing out last minute. With its contemporary interiors, three terraces, two kitchens, and 40 windows, it's hard to imagine that no one's bought it. As of last Thursday, the place is off the market, making people wonder if he's given up a second time or if it finally sold. We'll know soon enough.
