Peter Carey Peterson
Oh, PC, the "Chuck Bass" of the series, who, when you think about it, was really ahead of his time in terms of sexual ambiguity. The Dwight School alum and grandson of billionaire and former US Secretary of Commerce Peter George Peterson (and step-grandson of the creator of Sesame Street) is a photographer now and was last spotted in the news in January 2018, when he platonically said "I do" to his bestie Quentin Esme Brown in Las Vegas, with none other than Tiffany Trump as his flower girl. He explained in an Instagram post at the time that though he and his friend have never been romantically involved, they "have taken a progressive step towards what [they] believe marriage should be" and would continue to date other people while supporting each other as "life partners." Love that for them!
