Sigourney Weaver: Style Evolution (PHOTOS)

Sigourney Weaver (née Susan) is nicknamed the “Sci-Fi Queen” for her numerous roles in space films such as "Aliens" and "Ghostbusters," but her red carpet style is nothing, but gorgeous and glamorous. She usually dresses in floor-length, arm-bearing gowns, and Weaver also has a knack of wearing styles before they become too trendy. Case in point: the two-time Golden Globe winner has worn pajama tops, sheer looks and jumpsuits on the red carpet years before it became popular.

As Weaver celebrates her 62nd birthday this Saturday, click through the gallery to see her red carpet style evolution.
