Lana Del Rey: Russian Fans May Be Out to Kill Me

Lana Del Rey is in fear for her life ... claiming a couple of Russian fan girls are so obsessed with her .. she's afraid they'll kill her.

Lana filed a set of restraining orders against Nataliia Krinitsyna and Iuliia Vladimirovna Pozdina ... claiming the two are fanatic stalkers who have hunted her down, screamed at her in public and even threatened her.

Lana says the Russkies have put rambling letters in her mailbox, threatening suicide and other violence.

Lana says things got so bad she had to move, but the girls found her new place and resumed sleeping outside her house and screaming her name in the middle of the night.

The singer says she's afraid the girls will kill her, and she's also hired a full-time bodyguard and off duty LAPD cops for protection.
