Gossip Girl: from book to screen.

From EW:

One of the immediate changes I noticed on the show was that the character of Jenny Humphrey (played by Taylor Momsen) doesn't have the big chest that she was best known for in the books.
We made a point of not writing Jenny's large chest into the script because we just felt we would be saddling — quite literally — a young actress with something that would prove to be difficult over time. Either we had to limit our casting pool to young actresses with enormous chests, or we would be asking a 14- or 15-year-old girl to go to work every day with a giant padded bra or chicken cutlets in her bra, and it didn't sit well with either of us. When we met Taylor, we just felt she was so interesting, and she brought another layer to Jenny in the way that she had a kind of intelligence and danger to her, in addition to being naïve and sweet and wanting to be a part of this world. You also felt like she could go All About Eve on Blair's ass any moment.

Can I just say, yet again, that I'm loving Gossip Girl?  (And, yes, I'm really guilty and embarrassed about how much I'm loving it.)  We watched a couple of episodes the other night, and I turned to Josh AT LEAST 14 times over the course of the episode to say, "OH.  MY.  GOD.  I love this show."
