Talk about a Speed demon. Marcia Diana Valentine of Huntington Beach, California, tried to mow down Sandra Bullock's hubby, Jesse James, with her Mercedes on Sunday after Bullock asked her apparently off-kilter "biggest fan" to leave the couple's home, the AP reports.

After hopping into her car and throwing it into reverse, Valentine, 45, "attempted to hit [James] three or four times," then sped away, says a spokesman for the county sheriff. James was not injured, and Valentine was found and arrested on Monday on charges of assault with a Lake House DVD deadly weapon.
