Just as there is a hierarchy of celebrities (from Leonardo DiCaprio to Corey Feldman), there is one for LA mansions as well. Some are famous for their big, bold, glamorous Hollywood histories and others...for having been reality TV settings. Case in point, the so-called Rock Star Mansion--the home at which INXS jammed on the CBS reality show Rock Star. It's tricked out, for sure with its grotto pool, waterfalls, water slide, floating tennis court, elevator and five-bedroom guest house.

And it continues to host its share of Hollywood parties. But 'Leonardo' it's not.
