A woman who authorities say is obsessed with Sandra Bullock was arrested after she allegedly tried to run over the actress’ husband outside the couple’s home.

Marcia Diana Valentine, 45, of Huntington Beach, Calif., tried to run over Jesse James, host of ”Monster Garage,” with her Mercedes after Bullock asked her to leave on Sunday, said Jim Amormino, an Orange County sheriff’s spokesman.

How the hell did she get a Mercedes?

”She jumped in the car, put it in reverse and accelerated in his direction,” he said.

Macho James was not injured, and Valentine fled before authorities arrived, he said. On earlier occasions, Bullock and James had found Valentine lying in front of their garage door, Amormino said.
