Gossip Girl co-stars, Leighton Meester and Sebastian Stan, are moving in together. Geez, Gossip Girl has spawned so many couples. It really is like an extended college dorm room in motion. Anyway, rumors are swirling that Leighton and Sebastian are so in love and are going to make it official by shacking up together. Sort of like Ed Westwick and Chace Crawford?

more photos of Leighton and Stan after the hop…

Page Six reports the two were spotted drinking rosé (fancy pants!) at some restaurant in Southampton, NY. Then like a page ripped right out of USWeekly, the two partied with Ashton Kutcher and Demi Moore at some nightclub called Lily Pond.

Awww. Do you think Leighton and Sebastian will last?
