Sandra Bullock's decision is irreversible, and her shoutout is 'DIVORCE!'

But what's keeping the Speed star from actually filing the papers? Ask potential ex hubby, Jesse James. He 'knew' something, and it could be hazardous to Bullock's reputation.

Yes, according to RadarOnline.com, the distraught actress is afraid that Jesse James will counter attack and reveal her innermost secrets. She'll probably have to wait till the intentsity dies down. Might work.

Sandra's been able to maintain a level of privacy and the last thing she wants is for her 'ghosts' to surface. Yet, in spite of Jamesy's efforts to win his wife back through numerous tactics of desperation, the latter just won't budge and is standing her ground.

And now, reports conclude that the womanizing wonder is back in rehab. You have a lot of work ahead of you, buddy!
