Claire Danes @ Stardust Premiere

Claire Danes paired her dangerously low in a black Azzaro by Vanessa Seward backless dress with Neil Lane diamonds at the Los Angeles premiere of Stardust on Sunday.

The Matthew Vaughn-directed fantasy film is based on the novella by Neil Gaiman. In the film, Danes play Yvaine, a star that transforms into a striking girl.

Not too far behind on the red carpet: Claire‘s British beau Hugh Dancy.

Stardust is in theaters nationwide on Friday, August 10.
