The singer, real name Elizabeth Woolridge Grant, alleges the women are obsessed with her, and she has branded them "fanatic stalkers".

Editors at TMZ.com report the Summertime Sadness hitmaker has even moved house to shake them off, but the fans managed to track down her new address.

Del Rey has reportedly told a judge she fears for her safety and has hired a full-time bodyguard and off-duty Los Angeles Police Department officers for protection.

The judge has since granted restraining orders, and the two women must stay 100 yards away from Del Rey and her home.
