Katie Cassidy Hot Style Pictures: Monte Carlo Movie Premiere Photos, Pics

Katie Cassidy Pictures: Katie Cassidy arrives at the "Monte Carlo" movie premiere held at AMC Loews Lincoln Square on June 23, 2011 in New York City.

While on a trip to Paris with her best friend and soon-to-be-stepsister, Grace is mistaken for a British socialite, resulting in all three young women flying to Monte Carlo for a charity ball, auction, and the chance for international romance. However, when a million-dollar necklace goes missing, Grace and her friends must scramble to find it before the auction is ruined and their identities are exposed.

"Monte Carlo" opens in theaters nationwide on July 1.
