Katy Perry – $4 Million, L.A.

Fireworks star Katy Perry is certainly living her teenage dream. Aside from her bold $280 million net worth, she also has a wise real-estate investment in a $4-million Mediterranean-style villa. Her mansion is a 4,700-square-foot dream home that’s filled with stone lines, granite, and marble. Aside from that, it also has a huge closet room, five bathrooms, and four bedrooms. We can’t imagine the home insurance she pays for it, much less the maintenance upkeep!
