While Jesse James mistresses continue to come out of the woodwork, scorned Sandra Bullock has been living in her Hollywood Hills home – alone – for a week.

That’s just a few miles from the house she shared with her husband, and the newly-crowned Oscar winner has gone to great lengths to stay on the down low.

Wednesday, Sandra left the Hollywood Hills house she’s living in now (and lived in before marrying Jesse), taking precautions before heading to … the garage.

Two of her assistants held up a tarp to block any shot from cameras.

Somebody appears quite serious about her privacy right now, and given the things her jackass husband is accused of, it’s pretty much impossible to blame her.

Sandra has rarely left, although various people have come in and out. She has not been back to the Orange County house where Jesse lives since moving out.

According to sources, Sandra has no plans to return there unless he’s gone, either. Although he released a vague apology, that apparently hasn’t been enough.

There are rumors circulating that Bullock has met with divorce lawyers, though her rep has shot those down. You wonder if it’s only a matter of time, however.
