from www.tmz.com – Porn star Stormy Daniels is desperate for protection against her ex-husband — claiming the guy attacked her and her fiance at a red carpet event earlier this year … and even tried to steal her car.

Stormy — real name Stephanie Clifford — obtained a temporary restraining order this week in L.A. against her ex Michael Mosny, claiming Mosny also got her new fiance fired from his job … after threatening the man’s employer. Stormy claims Mosny even tried to have a friend steal her car.

Mosny and Daniels have a history of domestic violence — back in 2009, when they still lived together, the porn star was arrested for battery … after allegedly attacking Mosny over the way he did the laundry.

A hearing is set for December 22 to decide if the restraining order will be made permanent. Calls to Mosny had no comment.
