Serena van der Woodsen (Queen S) People compare her character with Josh Schwartz’s original it-girl creation, Marissa Cooper, stating that Serena “seems to have it all, but in addition to a party girl reputation, dark family secrets and a disregard for high society, Serena one-ups the sulky Coop with a history of BFF betrayal.”  Jason Gay of Rolling Stone describes Serena as “the bad girl gone good(ish) who serves as Gossip Girl’s wobbly moral compass.” He added praise while describing her early strained relationship with Blair, stating, “Lively’s Serena is a former queen bee who mysteriously disappeared from campus, only to return and find her spiteful ex-best friend, Blair (Meester), in charge.” With regards to her character’s direction in the show, actress Blake Lively commented on her character’s adventurous storylines during an interview with NYLON saying “I feel ridiculous at times with her, because I’m, you know, killing someone or marrying someone, but I look like me. I’m like, ‘Oh, this is absurd.’ ”    Vogue magazine considers Lively’s upbringing to be advantageous to her character background and finds her “dazzling and worldly and optimistic”. Her mother, a former model from Georgia would dress her differently and her differing fashion choices drew the attention of her classmates from the L.A. private school she enrolled in. “It was the only school where people were just downright mean to me,” Lively stated. “They would make fun of my clothes because I dressed differently than the other kids.” 
Blair Cornelia Waldorf ( Queen B ) In the first book, Blair is introduced as a privileged, comically vain overachiever. She is described as an alluring brunette, and occasionally models her appearance and demeanor after famous actresses, including Marilyn Monroe and, frequently, Audrey Hepburn. In early novels, the character is also written as bulimic. Blair is largely motivated by matters surrounding family, romance, and ambition. However, her tendency to overachieve can lead to feelings of paranoia, with dramatic or comic results. In a review for The New Yorker, Janet Malcolm remarked that Blair’s issues made her “both a broader caricature and a more real person” than the other Gossip Girl characters. In a 2009 interview, Gossip Girl creator Cecily von Ziegesar claimed to identify with Blair the most. “She is so unpredictable and dramatic. Such a bitch, but we understand why she is a bitch and we like her anyway”.
