Sheryl Crow and movie mogul Harvey Weinstein have each been granted three-year restraining orders against a man accused of harassing them.

Phillip Gordon Sparks was ordered to temporarily stay away from the All I Wanna Do hitmaker last month after he claimed Crow had stolen money from him and reportedly threatened to harm the star in a series of angry posts online.

It emerged this week that homeless Sparks had targeted Weinstein after becoming convinced the Hollywood producer had teamed up with Crow to rob him and destroy his life.

In a California court on Tuesday, a psychiatrist testifying on Crow's behalf called Sparks "dangerous", and a judge granted the singer - as well as Weinstein - a three-year restraining order.

Sparks has been ordered to refrain from contacting the singer, her family, her manager and other employees until 2015. (CL/PA&WNWE/KL)
