cory montieth monte carlo t 'Monte Carlo': Selena Gomez and Leighton Meester switch it upAfter “Gossip Girl” and “The Roommate,” we’re not really accustomed to seeing Leighton Meester play the goodie-two-shoes, but she does just that in this trailer for her upcoming film “Monte Carlo,” with Selena Gomez, Katie Cassidy, and “Glee’s” Cory Monteith.

The film is about three regular girls who go to Paris for their dream vacation after high school graduation… but they can’t exactly spring for first class. When they discover that Selena Gomez’s character, Grace, has a rich and famous doppelganger named Cordelia, they pull a little switcheroo.

Makeovers, hijinks, and great first kisses with cute boys ensue — everything we want in a teen rom-com romp. What do you think of this first look at the highly anticipated movie, which our fave teen TV stars shot last summer? Good news is that it’s rated PG, so you can totally use quality time with your little sister as an excuse to hit the theaters when it’s released this summer.

And yes, that’s a twitpic from Monteith. We couldn’t resist including it.
