Selena Gomez is living the life in her new movie 'Monte Carlo.' There's only one catch -- the life isn't really hers. In the new trailer for the film, we see the pop singer and her co-stars Leighton Meester and Katie Cassidy getting into plenty of hilarious trouble assuming the life of a British heiress.

The video introduces Grace (Gomez), Megan (Meester) and Emma (Cassidy), three friends who embark on their dream trip to Paris. However, when they arrive, it's evident that things aren't going to go as planned.

The girls decide to take a walk around town and land in the lobby of a swanky hotel where Grace is mistaken for an heiress named Cordelia. Before they can tell the truth, the best friends indulge in an unbelievable trip to Monte Carlo, getting swept up in the lifestyles of the rich and famous.

'Glee' star Cory Monteith plays Emma's beau, and Pierre Boulanger stars as the guy who makes Grace reconsider her assumed identity. Will Grace risk losing everything for love? Decisions, decisions. At least Gomez can always fall back on Justin Bieber.

The trailer features Gomez's latest single, 'Who Says,' using the inspirational anthem as a soundtrack to the girls' mischievous adventures. Check out the 'Monte Carlo' trailer below and get ready for the film's release in theaters on July 1.
