Ed Westwick enjoys flirting with rich girls 

that doesnt sound like Ed Westwick at all.

Au contraire, that sounds very much like Master Westwick. He's not always the cute, down to earth guy who's worst crime is swearing jovially in a British accent. I've been waiting for something like this to come out of him.

HOWEVER, I don't think he meant it quite as badly as it sounds. He didn't mean if they were as affluent as Blair and Serena, he meant if they were as much of a character as Blair and Serena both are... if that makes sense?
