Blair Waldorf ( Leighton Meester), a.k.a the Upper East Side’s Queen B., is a Gossip Girl fan favorite thanks to her exquisite style and her deliciously devious ways. In a new promo, set to Christina Aguilera‘s “Keeps Gettin’ Better,” the CW packs the best of Blair — the cat fights, the scheming, the sex, the headbands, the hatred of Chuck Bass (Ed Westwick) — into a 30 second clip. As Blair herself says, “Cheating, drinking, drugs — it’s all fair game.”

And while frenemy Serena van der Woodsen (Blake Lively) tells her, “Not everyone wants to be Blair Waldorf,” everyone certainly wants to watch her.
