The Hard Rock Cafe co-founder owns this property. In addition, the mansion previously was owned by media mogul and philanthropist David Geffen and before that, by actress Marlo Thomas.
Sandra Bullock (allegedly) recently purchased this property through a Mississippi-based business entity set up for the express purchase of a domestic residence via a New Orleans based attorney.
