"Gossip Girl" Fans: So Inappropriate!

The Parents Television Council got pissed at the soap's racy "OMFG" ad campaign -- and now we kinda get why.

Spotted: The cast of the show getting completely surrounded by a group of tweenage girls ... not exactly the best audience for threesomes, drug abuse and underage drinking.

Not that we're ones to judge. xoxo, Gossip Girl.
