The side entrance pops open with a bang and Selena Gomez, Leighton Meester and Katie Cassidy – intent upon escaping their tour group tour – come bursting out, rushing down steps. The director, Tom Bezucha, shouts “Cut!,” and the girls dissolve into giggles before, arms around each other, resuming their places for another take.

It was the scene at the Eiffel Tower early Monday morning as the shooting of Monte Carlo, a romantic comedy costarring Glee’s Corey Monteith, set for release next year.

After seven weeks filming together inside Budapest studios, one on set source tells PEOPLE, they couldn’t wait to get outside – even in near freezing temperatures. ‘They really get along really well. You can see they’ve gotten to be friends on this … It’s like a trip that way. There’s this chemistry and sometimes it’s almost conspiratorial, but these girls really adore each other.”
