A potential new pairing has the rumor mills swirling in New York City. 'Gossip Girl' star Blake Lively and 'Blue Valentine' actor Ryan Gosling have been spotted several times together--and they've been looking awfully cozy.

The pair was most recently seen at the 'Blue Valentine' after-party Thursday night, according to PEOPLE. Sources say they were nearly inseparable at the event held at The Top of the Standard at the Standard Hotel in NYC. One eyewitness said that even when Gosling started to walk away at one point, Lively grabbed him to keep talking.

After the party, Lively and Gosling went to the hotel restaurant, Standard Grill, and dined with two other friends.

The couple was first spotted together at Disneyland in October.

When asked about Lively, Gosling didn't admit much. "She's an incredible actress; she's a good friend," Gosling told PEOPLE.
