"Hanna Montana" is back from the dead! 

Miley Cyrus posted a new picture via Twitter of her rocking those signature long locks on Tuesday.

But before we get too excited, the 20-year-old was just getting in the Halloween spirit by trying on some different hairpieces. The "Wrecking Ball" singer tweeted "Wigzzzzz," along with the cute pic. 

Could a costume of her Disney alter-ego be in the works? Because that would be awesome.

We think the former Disney star looks gorgeous with longer, more natural looking tresses -- it's definitely a nice change from the Gwen Stefani (circa 1990s) look she's been rocking this past year.
