Sandra Bullock ... Gone Hollywood Without Jesse

Sandra Bullock has been living in her Hollywood Hills home since last Wednesday -- miles from the home she shared with Jesse James -- and she has gone to great lengths to stay on the down low.

Last Wednesday, Sandra left the Hollywood Hills house she owned before marrying Jesse, but before she walked into the garage, two of her assistants held up a tarp to block the shot of cameras.

She has not been back to the Orange County house where Jesse lives since moving back to Hollywood.

Sandra has rarely left the house since last Wednesday, although various people have come in and out.
