The proof it really is Miley? The picture below:
However I still believe it's a poser. First of all? She is Miley Cyrus. If she wanted a superstar account, with thousands of Starpoints, I'm sure Stardoll would accept the deal faster than you can say "Real Celeb". Then, if she really is Miley, why has she been on Stardoll 2 hours ago? She has to make her new movie plus the new Hannah Montana season and of course, stroll around Beverly Hills to have 20 papparazzi following her. And then, what if the picture above was photoshopped? Or if the poser just wrote the account ID on the picture and scanned it?
But what do you think? Poser or the Real Deal?
UPDATE: More proof this is a fake! Another account who claims to be Miley, Destiny--Cyrus, also posts the picture above as proof. Thanks to misslady690
