Kristen Stewart in Marchesa Dress Pictures at London Premiere of Snow White and the Huntsman

Kristen Stewart looked gorgeous at the UK premiere of Snow White and the Huntsman held at London's Empire Leicester Square yesterday. She glowed in a black lace Marchesa gown while her co-star Charlize Theron stunned in Christian Dior. Kristen spent the weekend outside of London doing press for SWATH but broke from her movie duties to celebrate boyfriend Robert Pattinson's birthday on Sunday. He continued the fun with a bash at Claridge's hotel on Sunday night, which included appearances from pals Sienna Miller and Hugh Jackman.
