Lily Collins has told how Julia Roberts helped allay her nerves - by telling her she would never banish them completely.
The young actress plays Snow White alongside Julia in the Tarsem Singh film Mirror Mirror.
She told Glamour magazine: "Julia was so lovely, and said, 'You know, no matter how much you've done this, you always have scenes that make you nervous, and psych you out the entire time'."
Lily added: "I was hoping it would go away! But it was quite a relief to know nerves don't just come from being new, they come from passion and really caring about something."
The actress, who also starred in Abduction, won Glamour's Breakthrough Woman Of The Year Award and attended the bash in central London.
Picking up her gong, she told the audience that she was proud to have "portrayed a character that's all about inner beauty and not concerned about physical appearance".
