Gossip Girl

Gossip Girl is the anonymous, unseen narrator of the Gossip Girl TV series. She is omniscient in every way and can be cruel in the way she reveals the secrets of the elite. In both the books and the show, Gossip Girl is a blogger whose true identity is unknown. She runs a blog documenting the lives of Manhattan's elite, or the wealthy teenagers residing in the Upper East Side. Posted on the blog are spotted characters, gossip and rumours. On the TV series, Gossip Girl is voiced by Kristen Bell. By the sound of each Gossip Girl's posts, it seems that she doesn't really like the Upper East Siders very much. You can really see this is the season 2 finale, "The Goodbye Gossip Girl", when she posts her own diplomas on the students:

"Not so fast. You're not graduating until i give you my diplomas. Mine are labels, and labels stick. Congratulations everyone. You deserve it."
