Lana Del Rey: My Jaguars Got Jacked!!

Lana Del Rey has some serious home security issues -- the singer had TWO luxury sports cars stolen out from under her nose within a week!

According to docs obtained by TMZ, a woman named Icess Floyd got into Lana's L.A. home in early November and made herself comfy for a couple days while Lana was out of town. Cops say she eventually bolted in Lana's 2013 Jaguar XK convertible, but ended up getting it impounded.

Here's the really ballsy part ... Floyd went back to the home and took off with a SECOND Jag, this time a 2015 F-TYPE! But during joyride #2, she got busted on an outstanding traffic warrant. Lana's car got impounded. Again.

Floyd was charged with 2 counts of burglary, and 2 counts of felony joyriding. Both of Lana's cars were returned. As we reported, a guy was busted for breaking into Lana's Malibu home earlier this week when she wasn't home.

House sitters wanted.
