The nice thing about celebrity real estate is that it's never-ending. There will always be someone famous dropping millions on a new luxury house that they'll probably only live in for a couple years before throwing it back on the market — or those like Katy Perry won't even move in before selling. While some people don't care whether an actress moved in down the street, many others find the prospect of a famous neighbor pretty exciting. Here's some of the most recent properties purchased and put on the market by the rich and famous, from Rod Stewart and Joaquin Phoenix to Taylor Swift and Claire Danes.
