This is the CW's creation of Serena and Blair's yearbook page. It is extremely funny.

Serena van der Woodsen (Blake Lively) and Blair Waldorf (Leighton Meester) are two of the most scandalous, cutest girls on the Upper East Side. These old friends are also rivals at points - particularly when S' past indiscretions with B's boyfriend are discussed.

Serena and Chuck were step-siblings for awhile. Now they're just friends, which makes his lewd comments slightly less offensive.

Serena van der Woodsen looking like Serena typically does. Gorgeous, and up to no good ... even if her intentions are.

A nice picture of Serena (Blake Lively) and Blair (Leighton Meester) in a future episode of Gossip Girl. We love both of these characters!

Serena and Eric in "While You Weren't Sleeping." The siblings have always been close.

In a scene from "The Blair Bitch Project," from the first season of Gossip Girl, Serena van der Woodsen (Blake Lively) and Blair Waldorf (Leighton Meester) have a conversation. They make a cute pair of pals, they do.

Lily, Serena, Blair and Nate look on as Chuck makes a scene at the funeral in "O Brother, Where Bart Thou?"

Or three on none? However Juliet, Serena and Blair want to play it, we're totally game.

Blair and Serena are going to be best friends for ever and ever and even infinity. So says this yearbook page.

Everyone is out to find Georgina in photo from "Woman on the Verge," from the first season of Gossip Girl. But will they get to the evil one in time?
