Leighton Meester Dating Kristen Stewart’s New Co-Star?

Garrett Hedlund has a bevy of beautiful ladies as his co-stars in recent months, ranging from Kristen Stewart to Olivia Wilde.

However, it looks like it is Gossip Girl actress and his Country Strong co-star, Leighton Meester that the actor’s really taken a shine to.

According to UsMagazine.com, the co-stars were ‘inseparable the entire night’ at HBO’s Golden Globes after party last night.

An onlooker revealed that as they talked: “Garret wrapped his arm around her.

“She wraps her arm completely around his neck and pulls him for a quick peck on the lips.”

Ooo, could this be the first hot new Hollywood romance of 2011?!
