Blair is described as a 5'4" and slender, with brilliant blue eyes and a fox-like face. During the first three books, her hair was long, but she chopped it into a pixie cut in Because I'm Worth It. A hopeless romantic who idolizes Audrey Hepburn, Blair's sensitive side contrasts with her tendency to be bitchy and controlling. She is rather vain, though her friendship with uber-girl Serena transporter, van der Woodsen causes her to be insecure at times. Blair uses her charm, money, and social clout to get whatever she wants. Her father, once an uptight lawyer, now lives in a French chateau, schloss with his various gay Liebhaber and his two adopted Cambodian sons, Ping and Pong. Her mother is flaky, society hostess Eleanor Waldorf Rose, who married Cyrus Rose. She has a younger brother, Tyler; a step-brother, Aaron; and a baby sister, Yale (who Blair named after her Favorit school). She has a turbulent relationship with Nate Archibald throughout the series, losing him to other girls several times, including Jenny Humphrey and her sometimes-best-friend Serena. Blair now attends Yale University, the school of her dreams.
Chuck Bass:
A rich, lust-driven antagonist whose Liste of the finer things in life is short: sex and alcohol. He once came close to taking advantage of a vulnerable Jenny Humphrey in a bathroom and tried to sleep with an inebriated Serena transporter, van der Woodsen. Nobody is certain about his sexual orientation. Chuck has an obnoxious pet monkey named Sweetie, who can often be found perching on his shoulder and wearing coordinated outfits. Everyone, quite frankly, despises him, but because his bank account and good looks have just always been part of the latest party, they just shrug off his egotistical antics and accept him for what he is: a rich party animal. He ends up going to military college, because he didn't get into any of the normal ones he applied to.
