Katy Perry: ~ $4 million, Los Angeles
Singer Katy Perry truly embodies her song, California Girl, with her Los Angeles address. She owns a 4,700-square-foot villa with a Mediterranean motif that features spectacular views of the city and its surroundings. At $4 million, it does seem like a steal, but there has been controversy regarding the property lately involving a group of old nuns, for which Katy needed the intervention of a lawyer.
