All celebrities must have the odd fan that just takes things a little bit too far. And for poor Miley Cyrus, it's not just her existing stalker that's causing trouble.

No, this mystery nutter has got seriously upset over Miley's decision to quit Twitter and has come up with a novel way of enticing her back.

We say novel, what we mean is sick and twisted. The fan in question is threatening to kill and eat their cat if Miley isn't back tweeting by November 16th.

Having set up a website entitled mileysavefuzzy.com, the superfan wrote: "The other day I asked myself: 'What can I do to bring Miley back to Twitter?' Fan video? Petitions? Letters? That never works. Heck, Miley even made her own video about never wanting to use Twitter again.

"Then I looked at my cat, Fuzzy and I realized, maybe Fuzzy can help. Fuzzy can make the ultimate sacrifice for this cause. It was very difficult for me, you see, as I sincerely love Fuzzy. But my mind is made up. I could always get another cat, but nothing can replace Miley's tweets for me!"

Clearly, it's an elaborate joke... but then again, anyone who is so obsessed with Miley's tweeting to think of such a dastardly plan and set up a website might just have the odd dangerously loose screw.

Sadly, Miley has recently experienced a frightening fan. And there's plenty of other celebrities with a stalker...
