Leighton Meester, Selena Gomez, & Katie Cassidy Promote ‘Monte Carlo’ (PHOTOS)

Leighton Meester, rocking her new bangs, was all smiles as she stepped out Thursday in New York for Monte Carlo press duties at the Ritz-Carlton.

Could her big grin have anything to do with the fact that she just came off a weekend hanging with her Country Strong costar and rumored real-life love interest Garrett Hedlund?

The two certainly looked like a very happy duo while hanging together in Los Angeles!

Meester’s Monte Carlo costar Selena Gomez was more business while entering the hotel, chatting on her phone (hey Justin Bieber?) and holding a large Starbucks in her hand.

Katie Cassidy looked chic in a sleeveless dress to her knees while making a graceful exit from her car before meeting up with her costars inside.

Monte Carlo hits theaters this Friday, July 1. Check it out!
