The almost 20-year old Panettierre came out for the NYC showing of her latest flick about a nerdy valedictorian who professes his love to her character during his graduation speech and gets exactly what he asks for -
- one wild night with the most popular girl in school. Sounds a little racy for high schoolers, but than again, this is the day and age of Gossip Girl. The premiere, hosted by Seventeen magazine, also included Hayden's co-stars Josh Emerson and Jack Carpenter. But we have a feeling that in her white, one shoulder dress by Andy & Deb and contrasting black shoes by Giuseppe Zanotti, no one was paying much attention to the boys.
