Why are they never together on Gossip Girl??? They have perfect chemistry!

CAUSE THE WRITERS ARE EVIL BITCHES!

Haha. I'm only half-kidding though.

Anyways, the writers know that Chace is a sex symbol. His part in the montrer is basically to stand there and look pretty. Therefore, they like him to have a lot of sex scenes (since most GG viewers are females, and toi know, sex sells). To get all those sex scenes, they have to have him hookup with a lot of chicks. Therefore, Natey boy can't get a serious gf (and Serena would definitely be a serious gf).
