Jenna Jameson was a crying mess after she crashed into a light pole early this morning ... telling people, "I just want to go home."
TMZ obtained the 911 call made by a woman who claims she witnessed the porn legend driving like a drunk person before she smashed her Range Rover into a pole in Orange County, CA just after midnight.
"I was actually getting ready to call you guys because she was drunk," the caller told the 911 operator ... adding, "Next thing I know she went into the pole."
The caller asked Jenna if she needed paramedics, to which she replied, "No, I just want to go."
She can later be heard wailing in the background, "I'm Jenna Jameson."
Three officers responded to the crash scene ... and as we first reported, Jenna was arrested for DUI. She has since been released.
