Most Ridiculous: Miley Cyrus channeled Julia Roberts from her Pretty Woman role, wearing a hooker-like outfit to the opening night of Britney Spears' Las Vegas show.

Best: Julia Roberts has made it clear over the last few years that she is over the red carpet thing, usually wearing dowdy dresses and pantsuits to her premieres, so it was pleasantly surprising to see her looking totally smashing in a animal print Gucci dress and heels with a Roger Vivier clutch at the Palm Springs International Film Festival. Well done.
