Cameron Diaz | $14.7 Million: Beverly Hills | $24,525: Toyota Prius

Now that they are new parents, it isn’t too surprising to find Cameron Diaz and Benji Madden paying top dollar for a new family home. The couple has upgraded to a bigger home in a more exclusive section of Beverly Hills, where they also happen to be neighbors with other celebs such as John Mayer and Vin Diesel. It was probably love at first sight when it comes to this property because they didn’t hesitate about paying the full asking price for it. Their latest investment comes with 1.7 acres of land, a mansion, and full-time security detail.

There’s also plenty of room if they ever decide to add to their car collection since the property comes with a three-car garage, with ample room for ten more. At the moment, however, Diaz is often spotted driving her Toyota Prius. This hybrid electric car is not only fuel-efficient but also very environmentally-friendly.
