Self-guided tours of L.A.?

Do you have to pay to tour areas where movie stars live in the Los Angeles area? Can I just rent a car and do a self-guided tour for free? Because those "movie star homes tours are sooo expenisve! Also, can I do a self-guided movie studio tour?

I have no idea about it but I had been Los Angeles couple of the times in my whole life to explore the beauty of this most amazing city and every time had huge fun there and came back with unforgettable memories. In my point of view, it is a perfect city for all kind of visitors. If you are travelling lover then I will suggest you must to be there at least once.  I hope you will spent good quality time there as well as other visitors.

I had explored Los Angeles personally and also had explored its some famous attractions while my tour. But I feel sad to say that I really don't have any idea about the area where celebrities live in Los Angeles. I hope any member has sufficient stuff and will like to share here with all of us.
