Blair Waldorf (full name: Blair Cornelia Waldorf) was born into high society on Manhattan's Upper East Side. Her father is Harold Waldorf, Esq., and her mother is Eleanor Waldorf.
The youngster is 5'4" and slender, with beautiful brown eyes. Blair is also a hopeless romantic who idolizes Audrey Hepburn, classic movies and upscale traditions, but whose sensitive side often clashes with her tendency to be bitchy and controlling.
Blair Waldorf is vain, though her friendship with Serena van der Woodsen (Blake Lively) causes her to be insecure at times. Perhaps as a result, she has become known as Queen B - useing her charm, money and social clout to win people over.
Blair Waldorf's dad, once a uptight lawyer, now lives in a French chateau with his French lover, Roman, who was a model Eleanor used to work with. He brought Roman to New York for Christmas and after some initial friction, Blair warmed up to him and they invited her to spend the summer in France.
She has been through - and continues to experience the ups and downs of - a rather turbulent relationship with boyfriend Nate Archibald (Chace Crawford) throughout the series, losing him to other girls several times, including Jenny Humphrey (Taylor Momsen) and even Serena. In fact, Serena's tryst with Nate was thought to be the reason S left town - and still looms large over their friendship.
After an uncharacteristic night in which she performed at a burlesque club on a whim, Blair Waldorf lost her virginity to Chuck Bass (Ed Westwick) in the back of his father's limo.
She proceeded to keep this secret affair going for a bit, but it blew up in her face and she was temporarily ousted as the school's social queen by Jenny Humphrey. She then went back to Nate after he finally showed some gumption at the ball. This upset Chuck, who is Nate's best friend and was starting to fall for Blair.
At the end of the first season of Gossip Girl, Blair and Chuck seemed to have a good thing going, only to have him return to his womanizing ways and throw it away. Can Chuck and Blair recapture the magic - or is this Queen Bee destined to find new love this year?
Blair: What are you still doing here Chuck? I threw you out hours ago.
Chuck: I wanted to let you know the treaty is over.
Blair: Fine with me. This pretense of civility was exhausting.
[to Jenny] That's the thing. You need to be cool to be queen. Anne Boleyn thought only with her heart and she got her head chopped off. So her daughter Elizabeth made a vow never to marry a man. She married a country. Forget boys. Keep your eye on the prize, Jenny Humphrey. You can't make people love you, but you can make them fear you. For what it's worth, you're my Queen. I choose you.Blair
