May: Charlie Sheen
In early 2011, Charlie Sheen was blowing up Twitter and news channels after his walk on the wild side. As if the former "Two and a Half Men" star's interesting comments weren't enough drama, leading to being fired from the show, Sheen also got busy hitting the real estate market by listing his Sherman Oaks home, above, for $7.2 million. In March, he picked up a home in the gated community of Mullholland Estates, a few blocks away, for $6,999,999. He wasn't selling because he's hard up on money: Sheen racked up about $40 million in the previous season of "Two and a Half Men."
