In papers submitted at Los Angeles County Superior Court on Wednesday (18May11), Price alleges that Prince Frederic Von Anhalt has been "showing up everywhere I was" in the past year.
Price claims Von Anhalt is "threatening me and scaring me" with a harassment campaign in messages and letters, and she's asked a judge to ban the star from coming near her.
She says, "I am scared for my life and my mom's life. This man does anything for press and I am afraid he will hurt me or have someone hurt us."
But Von Anhalt has vehemently denied the claims, telling TMZ.com, "If I hear one more false statement from her about me I will go to the West LA Police and file a criminal complaint against her myself!!"
