Blake Lively's 'Mom' Approves of Ryan Gosling

It's always good when your mom approves of your dating choices – even if it's just your onscreen mom.

With Ryan Gosling and Blake Lively apparently enjoying a special closeness, Kelly Rutherford – who plays Lively's mother on Gossip Girl – has given the pair the thumbs-up.

"It'd be great [if they were dating]. Blake's an amazing person," Rutherford said Friday at the opening of the new restaurant Beauty & Essex in New York. "She's so gorgeous. He's a lucky man if they are!"

Neither Gosling not Lively is admitting to anything serious between them. "She's an incredible actress; she's a good friend," Gosling told PEOPLE last week at a lunch for Blue Valentine in New York at the Kimberly Hotel.

Blake Lively & Ryan Gosling Get Cozy in NYC

Ryan Gosling’s new movie Blue Valentine almost got an NC-17 rating, but the actor kept the flirtation with Blake Lively noticeably G-rated at the film's premiere after-party.

Still, the pair were almost inseparable as they engaged in close conversation Thursday night while the event spun around them at The Top of the Standard at the Standard Hotel in New York. At one point, Gosling started to leave Lively’s side and the actress yanked him back to continue chatting, according to an observer.

As the party wound down, they headed downstairs to the hotel’s Standard Grill to dine with two other companions.

Lively, 23, and Gosling, 30, were first spotted together in October at Disneyland where they took in the sights and some ice cream at the park, an appropriate setting since Gosling once was a Mouseketeer.

Neither of the actors is admitting to anything serious. "She's an incredible actress; she's a good friend," Gosling told PEOPLE at a lunch Thursday for Blue Valentine in New York at the Kimberly Hotel.

When asked generally about romances between actors and actresses, Gosling says, "You're not allowed to have friends in this business."
