HitMiley Cyrus looks radiant and appropriately grown-up at the premiere of the much-anticipated Hannah Montana: The Movie in Hollywood. We love that she matched her sassy fringe dress with a fun leather jacket and boots.

MissMitchel Musso, who is starring in Hannah Montana: The Movie is too emo for the red carpet at the movie's premiere. And, while we can't deny that Dancing with the Stars' Shawn Johnson is as cute as a button, we're not feeling the beat of this busy spring frock.

MissMarg Helgenberger visits The Late Show with David Letterman to promote CSI's 200th episode. With all that crime-fighting under her belt, she should know that this outfit would get her arrested by the fashion police.
