Rachel McAdams was the life of the party on Friday night as the cast and crew of Midnight in Paris celebrated the end of their shoot on a boat docked on the Seine River. She arrived on the back of a motorcycle driven by a guy friend, then Rachel proceeded to chat and dance her way through the bash. Rachel logged a few late nights on set with her costar Owen Wilson, but she's also been able to do some exploring during her time in France. There are only a few weeks to go until Rachel starts work on The Vow with Channing Tatum, and it looks like she's getting a head start on her vacation fun.
