Mr Rumsey was later taken to the Clark County Jail and charged with making threats.
Miley's crazed fan is just one thing in a long list of issues at the moment as it's believed she's recently split from her girlfriend Kaitlynn Carter after less than two months of dating because they wanted to focus on their individual careers.
An insider said: "Miley and Kaitlyn broke up. They're still friends. They've been friends forever and were there for each other when they were both getting separated, but they're just not in a romantic relationship anymore."
Their relationship came just weeks after she split from her husband Liam Hemsworth.
Despite speculation that she had cheated on the 29-year-old movie star, Miley was adamant that she did everything she could to make their marriage work.
She said at the time: "I can accept that the life I've chosen means I must live completely open and transparent with my fans who I love, and the public, 100% of the time. What I cannot accept is being told I'm lying to cover up a crime I haven't committed. I have nothing to hide. (sic)"
