Can You Guess Which Celebrity Lives in This Mansion?

Well, we should really say "lived," as a now-divorced celebrity couple once owned this Hollywood Hills mansion together. Like the newly single songstress, who recently broke up with her fellow pop performer boyfriend, this mansion is now on the market. 

Although some might chalk it up to bad memories, the nine-time Grammy nominee actually ended her first and only marriage a long time before their home was put up for sale, and she and her actor / comedian ex hubby seem to be on pretty good terms lately anyways.
