Imagine a Gossip Girl movie? Kelly Rutherford has! “I was wondering if they’d do a movie,” she told us when we brought it up at a cocktail party for Elle Decor’s fashion issue hosted by John Demsey. “I don’t know, we’ll see if we can get Blake [Lively] on. I think it would be a lot of fun for everyone.” What about doing the movie without Blake? we ventured. “I don’t know,” Rutherford said. “Blake was so amazing in Gossip Girl, I don’t know — it’d be hard. So much of the story line was based around her and her experience, so I don’t know if it would work without Blake.” She’s right.
