Porn star Jenna Jameson has obtained a restraining order against a former friend amid allegations he has repeatedly broken into her California home and threatened to destroy her career.

The adult actress, 40, claims Allen Dean Clayborn has been attempting to blackmail her after a falling out, when he allegedly stole her keys and took cash from her house.

Jameson was so worried, she filed legal papers to protect her and her kids with ex-fiance Tito Ortiz, and the request has since been granted.

The judge presiding over the case has now ordered Clayborn to stay at least 100 yards (91.44 metres) away from Jameson, her family, her home and her sons' school, reports Tmz.com.
