Miley Cyrus is so Britney 2.0 - and why? They're both Southern belles slash Disney princesses! Of course, Miley has been flashing LiLo's peace sign for a long while now, but she's definitely not next in line for Lindsay's throne. Who is?

Why her little sis Ali! After all, the 14-year-old has been pretty open about her hunger for fame... and she just might get her chance with mom Dina's new reality show!

Ah, Paris and Nicole. The original BFFs. Who could ever replace them?

It's a long shot, but what about Disney "sweethearts" Vanessa Hudgens and Ashley Tisdale? They may not be as scandalous as our beloved heiresses (nude pictures and a nose job aren't really up there with DUIs and prison), but they are best friends... and nothing could ever tear them apart.

Right?
