The actress wore a black sequin and lace Zuhair Murad jumpsuit which featured sheer panelling and a large cut-out back.
She wore a nude dress by the Lebanese designer for the Los Angeles premiere which featured a strapless bodice and a lacy skirt, but this time opted for a more gothic look.
To compliment the dress, Stewart opted for a classic smokey eye and wore her hair in loose curls.
Stewart's co-star and rumoured boyfriend Robert Pattinson looked dapper in a Burberry suit with a grey shirt.
Taylor Lautner went for a navy suit and eschewed a traditional shirt and tie for a black v-neck t-shirt.
Also in attendance was Pixie Geldof, who has just announced that she is pregnant with her second child. She chose a plunging, scarlet evening dress for the premiere.
