Katy Perry: $4 Million, Los Angeles
Katy Perry shows her true California Girl colors with this $4 million mansion made of marble, stone lines, and granite. Covering 4,700 square feet, the home consists of 4 bedrooms, 5 bathrooms, and a large walk-in closet that actually used to be a 3-car garage! Perry’s estate also features a super-large pool with a gorgeous view. It is a pity that Perry spends so little time in this magnificent home, given how much time she spends touring the world.

Will Smith: $42 Million, California
This ultimate mansion belongs to Will Smith and his wife Jada Pinkett. It is so large it wouldn’t be surprised if it had its own zip code altogether. They paid $20 million for it but a few years ago it was rumored that they were selling it or $42 million, although nothing was confirmed. Some of the things featured on the estate are a recording studio, a golf course, and a basketball court, as well as a huge garage.
