“Gossip Girl” parents are usually involved with their own chaotic drama, as Nate Archibald’s had financial and legal issues, Serena van der Woodsen’s mother had multiple relationships and health scares, and Chuck Bass’ family occasionally tried committing murder.
Unlike her peers, Blair is pretty close with both of her parents. Her mother, Eleanor Waldorf, can sometimes be too busy with work to care for her, but her father, Harold Waldorf, adores her and always makes time for her when he’s in the country.
