The former Hannah Montana star vented her anger on Twitter after being trailed by photographers in Los Angeles.
"How is it legal for men I've never seen before to sit in front of my house and then follow me around," she asked. "So shady and scary."
Miley's tweet came during her brother Braison's brief hospital stint at the weekend, the result of an artery opening up following an operation to remove his tonsils.
Miley later scolded their father Billy Ray Cyrus for tweeting a picture of Braison covered in blood in a hospital bed following his release, stating: "Braisons gonna kill u for postinnnn that".
She had also lashed out against the press on Twitter earlier in the week, declaring: "I hate paparazzi with a passion. disgusting pigs. (no offence to pigs)."
